Abstract: 34 pp. (1996)., 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 $10< Q~2 < 160$GeV$~2$ 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 $\,\,$ , 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 $\,\,$ for LRG events with a hadronic mass $M_X$, which excludes the forward produced baryonic system, is similar to the $\,\,$ value observed in fixed target experiments at $W \approx M_X$.

Abstract: 16 pp. (1995)., This paper reports the cross section measurements for the process ep → e J/ψ p for Q 2 < 4 GeV 2 at s = 296 GeV, based on an integrated luminosity of about 0.5 pb −1 , using the ZEUS detector. The J/ψ was detected in its e + e − and μ + μ − decay modes. The photoproduction cross section was measured to be 52 −12 +7 ± 10 nb at an average γp 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: 23 pp. (1995)., 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 $1280 {\rm\ GeV}~2$. 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 \linebreak coherence effects in DIS and are compared with corresponding \eedata in order to test the universality of quark fragmentation.

Abstract: 14 pp. (1995)., We report the first observation of charmed mesons with the ZEUS detector at HERA using the decay channel D ∗+ → (D 0 → K − π + )π + (+c.c.) . Clear signals in the mass difference ΔM=M( D ∗ )−M( D 0 ) as well as in the M ( Kπ ) distribution at the D 0 mass are found. The ep cross section for inclusive D ∗± production with Q 2 < 4 GeV 2 in the γp centre-of-mass energy range 115 < W < 275 GeV has been determined to be (32±7 −7 +4 ) nb in the kinematic region pt (D ∗ ) ≥ 1.7 GeV, |η( 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 σ(ep → c c X) = (0.45 ± 0.11 −0.22 +0.37 ) μb at s =296 GeV and 〈 W 〉 = 198 GeV. The average γp charm cross section σ(γp → c c X) is found to be (6.3 ± 2.2 −3.0 +6.3 ) μb at 〈 W 〉 = 163 GeV and (16.9 ± 5.2 −8.5 +13.9 ) μb 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: 17 pp. (1995)., The exclusive production of ϱ 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 GeV 2 for λ ∗ p centre of mass (c.m.) energies 40 to 130 GeV. The λ ∗ p → ϱ 0 p cross section exhibits a Q −(4.2±0.8 −0.5 +1.4 ) dependence and both longitudinally and transversely polarised ϱ 0 's are observed. The λ ∗ p → ϱ 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: 24 pp. (1995)., 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 ∼ ( 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: 16 pp. (1995)., Jet production in deep inelastic scattering for 120 < Q 2 < 3600 GeV 2 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 γ ∗ - 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 ( α s 2 ) perturbative QCD calculations, allow a precise determination of α s ( Q ) in three Q 2 -intervals. The values are consistent with a running of ifα s ( Q ), as expected from QCD. Extrapolating to Q = M Z 0 α s ( M Z 0 ) = 0.117 ± 0.005 (stat) −0.005 +0.004 (syst exp ) ± 0.007 (syst theory ).

Abstract: Physical review letters 75(6), 1006 - 1011 (1995). doi:10.1103/PhysRevLett.75.1006, Deep inelastic $e~-p$ scattering has been studied in both the charged-current (CC) and neutral-current (NC) reactions at momentum transfers squared, $Q~2$, between 400 GeV$~2$ and the kinematic limit of 87500 GeV$~2$ 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. For $Q~2 \simeq M_W~2$, where $M_W$ is the mass of the $W$ boson, the CC and NC cross sections have comparable magnitudes, demonstrating the equal strengths of the weak and electromagnetic interactions at high $Q~2$. The $Q~2$ dependence of the CC cross section determines the mass term in the CC propagator to be $M_{W} = 76 \pm 16 \pm 13$GeV., Published by APS, College Park, Md.

Abstract: 19 pp. (1995)., Inclusive jet differential cross sections for the reaction ep → jet + X at Q 2 below 4 GeV 2 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 < η jet < 2 and refer to jets at the hadron level with a cone radius of one unit in the η - θ 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 < η jet ( λp CMS) < 0. These measurements cover a new kinematic regime of the partonic structure of the photon, at typical scales up to ∼300 GeV 2 and photon fractional momenta down to x γ ∼ 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 η jet and E t jet distributions.

Abstract: 31 pp. (1995)., This paper presents an analysis of the inclusive properties of diffractive deep inelastic scattering events produced in $ep$ interactions at HERA. The events are characterised by a rapidity gap between the outgoing proton system and the remaining hadronic system. Inclusive distributions are presented and compared with Monte Carlo models for diffractive processes. The data are consistent with models where the pomeron structure function has a hard and a soft contribution. The diffractive structure function is measured as a function of $x_{\mathbb p}$, the momentum fraction lost by the proton, of $\beta$, the momentum fraction of the struck quark with respect to $x_{\mathbb p}$, and of $Q^2$. The $x_{\mathbb p}$ dependence is consistent with the form$ (1/x_{\mathbb p})^a$ where $a=1.30\pm0.08(stat)~{+0.08}_{-0.14}(sys)$ in all bins of $\beta$ and $Q^2$. In the measured $Q^2$ range, the diffractive structure function approximately scales with $Q^2$ at fixed $\beta$. In an Ingelman-Schlein type model, where commonly used pomeron flux factor normalisations are assumed, it is found that the quarks within the pomeron do not saturate the momentum sum rule.

Abstract: 45 pp. (1995)., A search for excited states of the standard model fermions was performed using the ZEUS detector at the HERA electron-proton collider, operating at a centre of mass energy of 296 GeV. In a sample corresponding to an integrated luminosity of 0.55 pb−1, no evidence was found for any resonant state decaying into final states composed of a fermion and a gauge boson. Limits on the coupling strength times branching ratio of excited fermions are presented for masses between 50 GeV and 250 GeV, extending previous search regions significantly.

Abstract: 9 pp. (1995)., This paper presents measurements of \k\ and \lam\ production in neutral current, deep inelastic scattering of 26.7 GeV electrons and 820 GeV protons in the kinematic range $ 10 < Q~{2} < 640 $ GeV$~2$, $0.0003 < x < 0.01$, and $y > 0.04$. Average multiplicities for \k\ and \lam\ production are determined for transverse momenta \ \ptr\ $> 0.5 $ GeV and pseudorapidities $\left| \eta \right| < 1.3$. 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's in events with and without a large rapidity gap with respect to the proton direction are compared. The ratio of neutral \k's to charged particles per event in the measured kinematic range is, within the present statistics, the same in both samples.

Abstract: 15 pp. (1995)., Photoproduction at HERA is studied in ep collisions, with the ZEUS detector, for γp centre-of-mass energies ranging from 130–270 GeV. A sample of events with two high- p T jets ( p T > 6 GeV, η < 1.6) and a third cluster in the approximate direction of the electron beam is isolated using a clustering algorithm. These events are mostly due to resolved photoproduction. The third cluster is identified as the photon remnant. Its properties, such as the transverse and longitudinal energy flows around the axis of the cluster, are consistent with those commonly attributed to jets, and in particular with those found for the two jets in these events. The mean value of the photon remnant p T with respect to the beam axis is measured to be 2.1 ± 0.2 GeV, which demonstrates substantial mean transverse momenta for the photon remnant.

Abstract: Physics letters / B 338(4), 483-496 (1994). doi:10.1016/0370-2693(94)90804-4, Energy flows in deep inelastic electron-proton scattering are investigated at a centre-of-mass energy of 269 GeV for the range $Q^2 ≥ 10 \text{ GeV}^2$ 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 eents compared to the events without a large rapidity gap., Published by North-Holland Publ., Amsterdam
