Abstract: The production of D* ± (2010) mesons in e± p scattering in the range of exchanged photon virtuality 0.05 < Q2 < 0.7 GeV2 has been measured with the ZEUS detector at HERA using an integrated luminosity of 82 pb-1. The decay channels D* + → D0 π+ with D0 → K- π+ and corresponding antiparticle decay were used to identify D* mesons and the ZEUS beampipe calorimeter was used to identify the scattered electron. Differential D* cross sections as functions of Q2, inelasticity, y, transverse momentum of the D* meson, pT (D*), and pseudorapidity of the D* meson, η (D*), have been measured in the kinematic region 0.02 < y < 0.85, 1.5 < pT (D*) < 9.0 GeV and | η (D*) | < 1.5. The measured differential cross sections are in agreement with two different NLO QCD calculations. The cross sections are also compared to previous ZEUS measurements in the photoproduction and DIS regimes. © 2007 Elsevier B.V. All rights reserved.

Abstract: Diffractive photoproduction of D*+/-(2010) mesons was measured with the ZEUS detector at the ep collider HERA, using an integrated luminosity of 78.6 pb^{-1}. The D* mesons were reconstructed in the kinematic range: transverse momentum p_T(D*) > 1.9 GeV and pseudorapidity |eta(D*)| < 1.6, using the decay D*+ -> D0 pi+_s followed by D0 -> K- pi+ (+c.c.). Diffractive events were identified by a large gap in pseudorapidity between the produced hadronic state and the outgoing proton. Cross sections are reported for photon-proton centre-of-mass energies in the range 130 < W < 300 GeV and for photon virtualities Q^2 < 1 GeV^2, in two ranges of the Pomeron fractional momentum x_pom < 0.035 and x_pom < 0.01. The relative contribution of diffractive events to the inclusive D*+/-(2010) photoproduction cross section is about 6%. The data are in agreement with perturbative QCD calculations based on various parameterisations of diffractive parton distribution functions. The results are consistent with diffractive QCD factorisation., LaTeX2e, 29 pages, 9 Postscript figures, 4 tables, minor revisions, accepted for publication in the European Physical Journal C

Abstract: Dijet and trijet production in deep inelastic ep scattering has been measured in the phase space region 10 < Q(2) < 100 GeV2 and 10(-4) < x(Bj) < 10(-2) using an integrated luminosity of 82 pb(-1) collected by the ZEUS experiment. The high statistics have made possible detailed studies of multijet production at low xBj. The dependence of dijet and trijet production on the kinematic variables Q(2) and x(Bj) and on the jet variables E-T,HCM(jet) and eta(jet)(LAB) is well described by perturbative QCD calculations which include NLO corrections. To investigate possible deviations with respect to the collinear factorisation approximation used in the standard pQCD approach, measurements of the correlations between the two jets with highest E-T,HCM(jet) have been made. At low x(Bj), measurements of dijet production with low azimuthal separation are reproduced by the perturbative QCD calculations provided that higher-order terms (O(alpha(3)(s))) are accounted for. Such terms increase the predictions of pQCD calculations by up to one order of magnitude when the two jets with the highest E-T,HCM(jet1,2) are not balanced in transverse momentum. This demonstrates the importance of higher-order corrections in the low-x(Bj) region.

Abstract: Charm production in deep inelastic scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 82 pb^{-1}. Charm has been tagged by reconstructing D^{*+}, D^0, D^{+} and D_s^+ (+ c.c.) charm mesons. The charm hadrons were measured in the kinematic range p_T(D^{*+},D^0,D^{+}) > 3 GeV, p_T(D_s^+)>2 GeV and |��(D)| < 1.6 for 1.5 < Q^2 < 1000 GeV^2 and 0.02 < y < 0.7. The production cross sections were used to extract charm fragmentation ratios and the fraction of c quarks hadronising into a particular charm meson in the kinematic range considered. The cross sections were compared to the predictions of next-to-leading-order QCD, and extrapolated to the full kinematic region in p_T(D) and ��(D) in order to determine the open-charm contribution, F_2^{c\bar{c}}(x,Q^2), to the proton structure function F_2., 46 pages, 9 figures, 10 tables, accepted for publication in JHEP

Abstract: The production of beauty quarks with a D*+- and a muon in the final state has been measured with the ZEUS detector at HERA using an integrated luminosity of 114 pb-1. Low transverse-momentum thresholds for the muon and D* meson allow a measurement of beauty production closer to the production threshold than previous measurements. The beauty signal was extracted using the charge correlations and angular distributions of the muon with respect to the D* meson. Cross sections for photoproduction and deep inelastic scattering are somewhat higher than, but compatible with, next-to-leading-order QCD predictions, and compatible with other measurements., Comment: Second submission: 36 pages, 7 figures, 3 tables, minor revisions, accepted by European Physical Journal C

Abstract: Mean values and differential distributions of event-shape variables have been studied in neutral current deep inelastic scattering using an integrated {luminosity} of 82.2 pb$^{-1}$ collected with the ZEUS detector at HERA. The kinematic range was $80 < Q^2 < 20 480\gev^2$ and $0.0024 < x < 0.6$, where $Q^2$ is the virtuality of the exchanged boson and $x$ is the Bjorken variable. The data are compared with a model based on a combination of next-to-leading-order QCD calculations with next-to-leading-logarithm corrections and the Dokshitzer-Webber non-perturbative power corrections. The power-correction method provides a reasonable description of the data for all event-shape variables studied. Nevertheless, the lack of consistency of the determination of $��_s$ and of the non-perturbative parameter of the model, $\albar$, suggests the importance of higher-order processes that are not yet included in the model., 35 pages, 11 figures

Abstract: Photoproduction events which have two or more jets have been studied in the W-gamma P range 135 GeV < W-gamma P < 280 GeV with the ZEUS detector at HERA, A class of events is observed with little hadronic activity between the jets, The jets are separated by pseudorapidity intervals (Delta eta) Of up to four units and have transverse energies greater than 6 GeV. A gap is defined as the absence between the jets of particles with transverse energy greater than 300 MeV. The fraction of events containing a gap is measured as a function of Delta eta. It decreases exponentially as expected for processes in which colour is exchanged between the jets, up to a value of Delta eta similar to 3, then reaches a constant value of about 0.1. The excess above the exponential fall-off can be interpreted as evidence for hard diffractive scattering via a strongly interacting colour singlet object.

Abstract: The production of phi mesons in the reaction e(+)p --> e(+)phi p (phi --> K+K-) at a median Q(2) of 10(-4) GeV2 has been studied with the ZEUS detector at HERA. The differential phi photoproduction cross section d sigma/dt has an exponential shape and has been determined in the kinematic range 0.1 < \t\ < 0.5 GeV2 and 60 < W < 80 GeV. An integrated cross section of sigma(gamma p-->phi p) = 0.96+/-0.19(-0.18)(+0.21) mu b has been obtained by extrapolating to t = 0. When compared to lower energy data, the results show a weak energy dependence of both sigma(gamma-->phi p) and the slope of the t distribution. The phi decay angular distributions are consistent with s-channel helicity conservation. From lower energies to HERA energies, the features of phi photoproduction are compatible with those of a soft diffractive process.

Abstract: Elastic photoproduction of vector mesons, gamma p --> Vp, has been extensively studied in fixed target experiments at centre-of-mass energies up to W approximate to 20 GeV. The production of rho(0), omega and phi is usually described in the framework of the vector meson dominance model (VDM) [1] and Regge theory [2]. The W dependence of the cross section can be parametrised in Regge theory by the sum of two terms, one due to Pomeron exchange and the other to Reggeon exchange, While the latter falls with W, the former is almost flat, Whereas rho(0) and phi production is predominantly due to Pomeron exchange at all energies, the energy behaviour of omega production investigated before HERA suggests a non-negligible contribution from Reggeon exchange. It is therefore of interest to analyse omega photoproduction at HERA, where Pomeron exchange should dominate. More specifically, it is important to establish if the features typical of elastic rho(0) and phi vector meson production are also observed in omega photoproduction at high energy. Among these features are the weak dependence of the elastic cross section on W, the exponential shape of the differential cross section in t, where t is the squared four momentum transferred at the proton vertex, and the observation that the vector meson retains the helicity of the photon (s-channel helicity conservation, SCHC), In addition, a comparison of the photoproduction cross sections of the light vector mesons rho(0) [3, 4], omega and phi [5] at HERA energies allows another check of their diffractive production mechanism. This paper reports a measurement of the photoproduction of omega mesons using the reaction ep --> e omega p with the ZEUS detector at HERA. The omega meson is observed via its decay into pi(+)pi(-)pi(0)(pi(0) --> gamma gamma) in the kinematic range 70 < W < 90 GeV and p(T)(2) < 0.6 GeV2, where p(T) is the transverse momentum of the omega with respect to the beam axis. For these events the scattered positron was not observed in the detector, thereby restricting the photon virtuality Q(2) to values smaller than 4 GeV2, with a median Q(2) of about 10(-4) GeV2.

Abstract: We present measurements of the structure function F-2 in e(+)p scattering at HERA in the range 3.5 GeV2 < Q(2) < 5000 GeV2. A new reconstruction method has allowed a significant improvement in the resolution of the kinematic variables and an extension of the kinematic region covered by the experiment. Ac Q(2) < 35 GeV2 the range in x now spans 6.3 . 10(-5) < x < 0.08 providing overlap with measurements from fixed target experiments. At values of Q(2) above 1000 GeV2 the x range extends to 0.5. Systematic errors below 5% have been achieved for most of the kinematic region. The structure function rises as x decreases; the rise becomes more pronounced as Q(2) increases. The behaviour of the structure function data is well described by next-to-leading order perturbative QCD as implemented in the DGLAP evolution equations.

Abstract: The production of phi mesons in the reaction e(+)p --> e(+)phi p (phi --> K+K-), for 7 < Q(2) < 25 GeV2 and for virtual photon-proton centre of mass energies (W) in the range 42-134 GeV, has been studied with the ZEUS detector at HERA. When compared to lower energy data at similar Q(2), the results show that the gamma*p --> phi p cross section rises strongly with W. This behaviour is similar to that previously found for the gamma*p --> rho(0)p cross section. This strong dependence cannot be explained by production through soft pomeron exchange, It is, however, consistent with perturbative QCD expectations, where it reflects the rise of the gluon momentum density in the proton at small x. The ratio of sigma(phi)/sigma(rho(0)), which has previously been determined by ZEUS to be 0.065 +/- 0.013 (stat.) in photoproduction at a mean W of 70 GeV, is measured to be 0.18 +/- 0.05 (stat.) +/- 0.03 (syst.) at a mean Q(2) of 12.3 GeV2 and mean W of approximate to 100 GeV and is thus approaching at large Q(2) the value of 2/9 predicted from the quark charges of the vector mesons and a flavour independent production mechanism.

Abstract: In deep inelastic neutral current scattering of positrons acid protons at the center of mass energy of 300 GeV, we observe, with the ZEUS detector, events with a high energy neutron produced at very small scattering angles with respect to the proton direction. The events constitute a fixed fraction of the deep inelastic, neutral current event sample independent of Bjorken x and Q(2) in the range 3 . 10(-4)

Abstract: A measurement of inclusive charged particle distributions in deep inelastic ep scattering for gamma*p centre-of-mass energies 75 < W < 175 GeV and momentum transfer squared 10 < Q(2) < 160 GeV2 from the ZEUS detector at HERA is presented. The differential charged particle rates in the gamma*p centre-of-mass system as a function of the scaled longitudinal momentum, x(F), and of the transverse momentum, p(t)* and [p(t)(*2)], as a function of x(F), W and Q(2) are given, Separate distributions are shown for events with (LRG) and without (NRG) a rapidity gap with respect to the proton direction. The data are compared with results from experiments at lower beam energies, with the naive quark parton model and with parton models including perturbative QCD corrections, The comparison shows the importance of the higher order QCD processes. Significant differences of the inclusive charged particle rates between NRG and LRG events at the same W are observed, The value of [p(t)(*2)] for LRG events with a hadronic mass M(X), which excludes the forward produced baryonic system, is similar to the [p(t)(*2)] value observed in fixed target experiments at W approximate to M(X).

Abstract: We report on a measurement of the proton structure function F-2 in the range 3.5 x 10(-5) less than or equal to x less than or equal to 4 x 10(-3) and 1.5 GeV2 less than or equal to Q(2) less than or equal to 15 GeV2 at the ep collider HERA operating at a centre-of-mass energy of root s = 300 GeV. The rise of F-2 with decreasing x observed in the previous HERA measurements persists in this lower x and Q(2) range. The Q(2) evolution of F-2, even at the lowest Q(2) and x measured, is consistent with perturbative QCD.

Abstract: Deep inelastic charged-current reactions have been studied in e(+)p and e(-)p collisions at a center of mass energy of about 300 GeV in the kinematic region Q(2)>200 GeV2 and x>0.006 using the ZEUS detector at HERA, The integrated cross sections for Q(2)>200 GeV2 are found to be sigma(e+p-->)=30.3(-4.2 -2.6)(+5.5 +1.6) pb and sigma(e-p-->upsilon X)=54.7(-9.8 -3.4)(+15.9 +2.8) pb. Differential cross sections have been measures as functions of the variables x, y and Q(2). From the measured differential cross sections d sigma/dQ(2), the W boson mass is determined to be M(W)=79(-7 -4)(+8 +4) GeV. Measured jet rates and transverse energy profiles agree with model predictions, A search for charged-current interactions with a large rapidity gap yielded one candidate event, corresponding to a cross section of sigma(e+p-->)(Q(2)>200 GeV2; eta(max)

Abstract: Jet photoproduction, where the two highest transverse energy (E(T)(jet)) jets have E(T)(jet) above 6 GeV and a jet-jet invariant mass above 23 GeV, has been studied with the ZEUS detector at the HERA ep collider. Resolved and direct photoproduction samples have been separated. The cross section as a function of the angle between the jet-jet axis and the beam direction in the dijet rest frame has been measured for the two samples. The measured angular distributions differ markedly from each other. They agree with the predictions of QCD calculations, where the different angular distributions reflect the different spins of the quark and gluon exchanged in the hard subprocess.

Abstract: The cross sections for charged and neutral current deep inelastic scattering in e + p collisions with a longitudinally polarised positron beam have been measured using the ZEUS detector at HERA. The results, based on data corresponding to an integrated luminosity of 23.8 pb -1 at sqrt(s) = 318 GeV, are given for both e + p charged current and neutral current deep inelastic scattering for both positive and negative values of the longitudinal polarisation of the positron beam. Single differential cross sections are presented for the kinematic region Q 2 > 200 GeV 2. The measured cross sections are compared to the predictions of the Standard Model. A fit to the data yields σ CC ( P e = - 1 ) = 7.4 ± 3.9 ( stat. ) ± 1.2 ( syst. ) pb, which is consistent within two standard deviations with the absence of right-handed charged currents in the Standard Model. © 2006 Elsevier B.V.

Abstract: Differential inclusive jet cross sections in neutral current deep inelastic ep scattering have been measured with the ZEUS detector. Three phase-space regions have been selected in order to study parton dynamics where the effects of BFKL evolution might be present. The measurements have been compared to the predictions of leading-logarithm parton shower Monte Carlo models and fixed-order perturbative QCD calculations. In the forward region, QCD calculations at order alpha_s^1 underestimate the data up to an order of magnitude at low x. An improved description of the data in this region is obtained by including QCD corrections at order alpha_s^2, which account for the lowest-order t-channel gluon-exchange diagrams, highlighting the importance of such terms in parton dynamics at low x., Comment: 25 pages, 4 figures

Abstract: Jet production in deep inelastic scattering for 120 < Q(2) < 3600 GeV2 has been studied using data from an integrated luminosity of 3.2 pb(-1) collected with the ZEUS detector at HERA. Jets are identified with the JADE algorithm. A cut on the angular distribution of parton emission in the gamma(8)-parton centre-of-mass system minimises the experimental and theoretical uncertainties in the determination of the jet rates. The jet rates, when compared to O(alpha(s)(2)) perturbative QCD calculations, allow a precise determination of alpha(s)(Q) in three Q(2)-intervals. The values are consistent with a running of alpha(s)(Q), as expected from QCD. Extrapolating to Q = M(Z0) yields alpha(s)(M(Z0)) = 0.117 +/- 0.005 (stat)(-0.005)(+0.004) (syst(exp)) +/- 0.007 (syst(theory)).

Abstract: Deep inelastic e-p scattering has been studied in both the charged current (CC) and neutral current (NC) reactions at momentum transfers squared Q(2) above 400 GeV2 using the ZEUS detector at the HERA ep collider. The CC and NC total cross sections, the NC to CC cross section ratio, and the differential cross sections d sigma/dQ(2) are presented. From the Q(2) dependence of the CC cross section, the mass term in the CC propagator is determined to be M(W) = 76 +/- 16 +/- 13 GeV.

Abstract: Elastic rho(0) photoproduction has been measured using the ZEUS detector at HERA. Untagged photoproduction events from ep interactions were used to measure the reaction gamma p --> rho(0)P (rho(0) --> pi(+)pi(-)) at photon-proton centre-of-mass energies between 60 and 80 GeV and \t\ < 0.5 GeV2, where t is the square of the four-momentum transferred at the proton vertex. The differential cross section d sigma/dM(pi pi), where M(pi pi) is the invariant mass of the two pions, and the integrated cross section, sigma(gamma p-->rho)o(p), are presented; the latter was measured to be 14.7 +/- 0.4 (stat.) +/- 2.4 (syst.) mu b. The differential cross section d sigma/dt has an approximately exponential shape; a fit of the type A'(t) exp (-b'(t)\t\ + c'(t)t(2)) yields a t-slope b'(t) = 9.9 +/- 1.2 (stat.) +/- 1.4 (syst.) GeV-2. The results, when compared to low energy data, show a weak energy dependence of both sigma(gamma p-->rho)o(P) and of the t-slope. The p(0) is produced predominantly with transverse polarisation, demostrating that s-channel helicity conservation holds at these energies.

Abstract: Charged particle production has been measured in Deep Inelastic Scattering (DIS) events using the ZEUS detector over a large range of Q(2) from 10 to 1280 GeV2 The evolution with Q of the charged multiplicity and scaled momentum has been investigated in the current fragmentation region of the Breit frame. The data are used to study QCD coherence effects in DIS and are compared with corresponding e(+)e(-) data in order to test the universality of quark fragmentation.

Abstract: The ZEUS detector has been used to measure the proton structure function F-2. During 1993 HERA collided 26.7 GeV electrons on 820 GeV protons. The data sample corresponds to an integrated luminosity of 0.54 pb(-1), representing a twenty fold increase in statistics compared to that of 1992. Results are presented for 7 < Q(2) < 10(4) GeV2 and x values as low as 3 x 10(-4). The rapid rise in F-2 as x decreases observed previously is now studied in greater detail and persists for Q(2) values up to 500 GeV2.

Abstract: This paper presents measurements of K-0 and Lambda production in neutral current, deep inelastic scattering of 26.7 GeV electrons and 820 GeV protons in the kinematic range 10 < Q(2) < 640 GeV2, 0.0003 < x < 0.01, and y > 0.04. Average multiplicities for K-0 and Lambda production are determined for transverse momenta p(T) > 0.5 GeV and pseudorapidities \eta\ < 1.3. The multiplicities favour a stronger strange to light quark suppression in the fragmentation chain than found in e(+)e(-) experiments. The production properties of K-0's in events with and without a large rapidity gap with respect to the proton direction are compared. The ratio of neutral K-0's to charged particles per event in the measured kinematic range is, within the present statistics, the same in both samples.

Abstract: Inclusive jet cross sections for events with a large rapidity gap with respect to the proton direction from the reaction ep --> jet + X with quasi-real photons have been measured with the ZEUS detector. The cross sections refer to jets with transverse energies E(T)(jet) > 8 GeV, The data show the characteristics of a diffractive process mediated by pomeron exchange. Assuming that the events are due to the exchange of a pomeron with partonic structure, the quark and gluon content of the pomeron is probed at a scale similar to (E(T)(jet))(2). A comparison of the measurements with model predictions based on QCD plus Regge phenomenology requires a contribution of partons with a hard momentum density in the pomeron. A combined analysis of the jet cross sections and recent ZEUS measurements of the diffractive structure function in deep inelastic scattering gives the first experimental evidence for the gluon content of the pomeron in diffractive hard scattering processes. The data indicate that between 30% and 80% of the momentum of the pomeron carried by partons is due to hard gluons.

Abstract: Inclusive jet differential cross sections for the reaction ep --> jet + X at Q(2) below 4 GeV2 have been measured with the ZEUS detector at HERA using an integrated luminosity of 0.55 pb(-1). These cross sections are given in the kinematic region 0.2 < y < 0.85, for jet pseudorapidities in the ep-laboratory range -1 < eta(jet) < 2 and refer to jets at the hadron level with a cone radius of one unit in the eta - phi plane. These results correspond to quasi-real photoproduction at centre-of-mass energies in the range 130-270 GeV and, approximately, for jet pseudorapidities in the interval -3 < eta(jet)(gamma p CMS) < 0. These measurements cover a new kinematic regime of the partonic structure of the photon, at typical scales up to similar to 300 GeV2 and photon fractional momenta down to x(y) similar to 10(-2). Leading logarithm parton shower Monte Carlo calculations, which include both resolved and direct processes and use the predictions of currently available parametrisations of the photon parton distributions, describe in general the shape and magnitude of the measured eta(jet) and E(T)(jet) distributions.

Abstract: Events with a large rapidity gap and total transverse energy greater than 5 GeV have been observed in quasi-real photoproduction at HERA with the ZEUS detector. The distribution of these events as a function of the gamma p centre of mass energy is consistent with diffractive scattering. For total transverse energies above 12 GeV, the hadronic final states show predominantly a two-jet structure with each jet having a transverse energy greater than 4 GeV. For the two-jet events, little energy flow is found outside the jets. This observation is consistent with the hard scattering of a quasi-real photon with a colourless object in the proton.

Abstract: We report the first observation of charmed mesons with the ZEUS detector at HERA using the decay channel D*(+) --> (D-0 --> K(-)pi(+)) pi(+) (+ c.c.). Clear signals in the mass difference Delta M=M(D*)-M(D-0) as well as in the M(K pi) distribution at the D-0 mass are found. The ep cross section for inclusive D*(+/-) production with Q(2) < 4 GeV2 in the gamma p centre-of-mass energy range 115 < W < 275 GeV has been determined to be (32+/-7(-7)(+4)) nb in the kinematic region {pr(D*) greater than or equal to 1.7 GeV, \pi(D*)\ < 1.5}. Extrapolating outside this region, assuming a mass of the charm quark of 1.5 GeV, we estimate the ep charm cross section to be sigma(ep --> c $($) over bar$$ cX)=(0.45+/-0.11(-0.22)(+0.37)) mu b at root s=296 GeV and [W]=198 GeV. The average gamma p charm cross section sigma(gamma p --> c $($) over bar$$ cX) is found to be (6.3+/-2.2(-3.0)(+6.3)) mu b at [W]=163 GeV and (16.9+/-5.2(-8.5)(+13.9)) mu b at [W]=243 GeV. The increase of the total charm photoproduction cross section by one order of magnitude with respect to low energy data experiments is well described by QCD NLO calculations using singular gluon distributions in the proton.

Abstract: Inclusive transverse momentum spectra of charged particles in photoproduction events in the laboratory pseudorapidity range -1.2 < eta < 1.4 have been measured up to P-T = 8 GeV using the ZEUS detector. Diffractive and non-diffractive reactions have been selected with an average gamma p centre of mass (c.m.) energy of (W) = 180 GeV. For diffractive reactions, the p(T) spectra of the photon dissociation events have been measured in two intervals of the dissociated photon mass with mean values (M(X)) = 5 GeV and 10 GeV. The inclusive transverse momentum spectra fall exponentially in the low p(T) region. The non-diffractive data p show a pronounced high p(T) tail departing from the exponential shape. The p(T) distributions are compared to lower energy photoproduction data and to hadron-hadron collisions at a similar c.m. energy. The data are also compared to the results of a next-to-leading order QCD calculation.

Abstract: The exclusive production of rho(0) mesons in deep inelastic electron-proton scattering has been studied using the ZEUS detector Cross sections have been measured in the range 7 < Q(2) < 25 GeV2 for gamma*p centre of mass (c.m.) energies from 40 to 130 GeV. The gamma*p --> rho(0)p cross section exhibits a Q(-(4.2+/-0.8-0.5+14)) dependence and bath longitudinally and transversely polarised rho(0)'s are observed. The gamma*p --> rho(0)p cross section rises strongly with increasing c.m. energy, when compared with NMC data at lower energy, which cannot be explained by production through soft pomeron exchange. The data are compared with perturbative QCD calculations where the rise in the cross section reflects the increase in the gluon density at low x.

Abstract: Two-jet production in deep-inelastic electron-proton scattering has been studied for 160 < Q(2) < 1280 GeV2 0.01 < x < 0.1 and 0.04 < y < 0.95 with the ZEUS detector at HERA. The kinematic properties of the jets and the jet production rates are presented. The partonic scaling variables of the two-jet system and the rate of two-jet production are compared to perturbative next-to-leading order QCD calculations.

Abstract: This paper reports the cross section measurements for the process ep --> e J/psi p for Q(2) < 4 GeV2 at root s = 296 GeV, based on an integrated luminosity of about 0.5 pb(-1), using the ZEUS detector. The J/psi was detected in its e(+)e(-) and mu(+)mu(-) decay modes. The photoproduction cross section was measured to be 52(-12)(+7) +/- 10 nb at an average gamma p centre of mass energy of 67 GeV and 71(-20)(+13) +/- 12 nb at 114 GeV. The significant rise of the cross section compared to lower energy measurements is not in agreement with VDM models, but can be described by QCD inspired models if a rise in the gluon momentum density at low x in the proton is assumed.

Abstract: Deep inelastic scattering and its diffractive component, ep -> e'gamma*p ->e'XN, have been studied at HERA with the ZEUS detector using an integrated luminosity of 4.2 pb-1. The measurement covers a wide range in the gamma*p c.m. energy W (37 - 245 GeV), photon virtuality Q2 (2.2 - 80 GeV2) and mass Mx. The diffractive cross section for Mx > 2 GeV rises strongly with W; the rise is steeper with increasing Q2. The latter observation excludes the description of diffractive deep inelastic scattering in terms of the exchange of a single Pomeron. The ratio of diffractive to total cross section is constant as a function of W, in contradiction to the expectation of Regge phenomenology combined with a naive extension of the optical theorem to gamma*p scattering. Above Mx of 8 GeV, the ratio is flat with Q2, indicating a leading-twist behaviour of the diffractive cross section. The data are also presented in terms of the diffractive structure function, F2D(3)(beta,xpom,Q2), of the proton. For fixed beta, the Q2 dependence of xpom F2D(3) changes with xpom in violation of Regge factorisation. For fixed xpom, xpom F2D(3) rises as beta -> 0, the rise accelerating with increasing Q2. These positive scaling violations suggest substantial contributions of perturbative effects in the diffractive DIS cross section., 87 pages, 25 figures

Abstract: A search for pentaquarks decaying to Xi^{-} pi^{-} (Xi^{-} pi^{+}) and corresponding antiparticles has been performed with the ZEUS detector at HERA. The data sample consists of deep inelastic ep scattering events at centre-of-mass energies of 300 and 318 GeV, and corresponds to 121 pb^{-1} of integrated luminosity. A clear signal for Xi^{0}(1530) to Xi^{-} pi^{+} was observed. However, no signal for any new baryonic state was observed at higher masses in either the Xi^{-} pi^{-} or Xi^{-} pi^{+} channels. The searches in the antiparticle channels were also negative. Upper limits on the ratio of a possible Xi^{--}_{3/2} (Xi^{0}_{3/2}) signal to the Xi^{0}(1530) signal were set in the mass range 1650-2350 MeV., Comment: 12 pages, 4 figures, submitted to Phys.

Abstract: Energy flows in deep inelastic electron-proton scattering are investigated at a center-of-mass energy of 296 GeV for the range Q2 greater-than-or-equal-to 10 GeV2 using the ZEUS detector. A comparison is made between events with and without a large rapidity gap between the hadronic system and the proton direction. The energy flows, corrected for detector acceptance and resolution, are shown for these two classes of events in both the HERA laboratory frame and the Breit frame. From the differences in the shapes of these energy flows we conclude that QCD radiation is suppressed in the large-rapidity-gap events compared to the events without a large rapidity gap.

Abstract: A resonance search has been made in the D*±p∓ invariant-mass spectrum with the ZEUS detector at HERA using an integrated luminosity of 126 pb-1. The decay channels D*+ -→ D0πs+ → (K -π+)πs+ and D*+ → D0πs+ → (K-π+π+π-) πs+ (and the corresponding antiparticle decays) were used to identify D*± mesons. No resonance structure was observed in the D*± p∓ mass spectrum from more than 60 000 reconstructed D*± mesons. The results are not compatible with a report of the H1 Collaboration of a charmed pentaquark, Θc0. © Springer-Verlag / Società Italiana di Fisica 2004.

Abstract: Cross sections for e+ p neutral current deep inelastic scattering have been measured at a center-of-mass energy of √s = 318 GeV with the ZEUS detector at HERA using an integrated luminosity of 63.2 pb -1. The double-differential cross section, d2σ/ dxdQ2, is presented for 200 GeV2 < Q2 < 30 000 GeV2 and for 0.005 < x < 0.65. The single-differential cross sections dσ/dQ2, dσ/dx and dσ/dy are presented for Q2 > 200 GeV2. The effect of Z-boson-exchange is seen in dσ/dx measured for Q2 > 10 000 GeV2. The data presented here were combined with ZEUS e+ p neutral current data taken at √s = 300 GeV and the structure function F2em was extracted. All results agree well with the predictions of the Standard Model.

Abstract: Jet substructure and differential cross sections for jets produced in the photoproduction and deep inelastic ep scattering regimes have been measured with the ZEUS detector at HERA using an integrated luminosity of 82.2 pb-1. The substructure of jets has been studied in terms of the jet shape and subjet multiplicity for jets with transverse energies Et(jet) > 17 GeV. The data are well described by the QCD calculations. The jet shape and subjet multiplicity are used to tag gluon- and quark-initiated jets. Jet cross sections as functions of Et(jet), jet pseudorapidity, the jet-jet scattering angle, dijet invariant mass and the fraction of the photon energy carried by the dijet system are presented for gluon- and quark-tagged jets. The data exhibit the behaviour expected from the underlying parton dynamics. A value of alphas(Mz) of alphas(Mz) = 0.1176 +-0.0009(stat.) -0.0026 +0.0009 (exp.) -0.0072 +0.0091 (th.) was extracted from the measurements of jet shapes in deep inelastic scattering., 67 pages, 17 figures, 24 tables

Abstract: A search for physics beyond the Standard Model has been performed with high-Q^2 neutral current deep inelastic scattering events recorded with the ZEUS detector at HERA. Two data sets, e^+ p \to e^+ X and e^- p \to e^- X, with respective integrated luminosities of 112 pb^-1 and 16 pb^-1, were analyzed. The data reach Q^2 values as high as 40000 GeV^2. No significant deviations from Standard Model predictions were observed. Limits were derived on the effective mass scale in eeqq contact interactions, the ratio of leptoquark mass to the Yukawa coupling for heavy leptoquark models and the mass scale parameter in models with large extra dimensions. The limit on the quark charge radius, in the classical form factor approximation, is 0.85 10^-16 cm., Comment: 28 pages, 4 figures, accepted for publication in Physics Letters B

Abstract: Inclusive KsKs production in deep inelastic ep scattering at HERA has been studied with the ZEUS detector using an integrated luminosity of 120 pb-1. Two states are observed at masses of 1537 (+9)(-8) MeV and 1726 +- 7 MeV, as well as an enhancement around 1300 MeV. The state at 1537 MeV is consistent with the well established f2'(1525). The state at 1726 MeV may be the glueball candidate f0(1710). However, it's width of 38 (+20)(-14) MeV is narrower than 125 +- 10 MeV observed by previous experiments for the f0(1710). Comment: 13 pages, 1 table and 3 figures. Updated with minor changes to the text requested by the journal referee. Accepted by Physics Letters B
