Abstract: A search in the H1 experiment at HERA for scalar and vector leptoquarks, leptogluons and squarks coupling to first generation fermions is presented in a data sample corresponding to an integrated luminosity of 425 nb−1. For masses ranging up to ∼275 GeV, no significant evidence for the direct production of such particles is found in various possible decay channels. At high masses and beyond the centre of mass energy of 296 GeV a contact interaction analysis is used to further constrain the couplings and masses of new vector leptoquarks and to set lower limits on compositeness scales.

Abstract: Global properties of the hadronic final state in deep inelastic scattering events at HERA are investigated. The data are corrected for detector effects and are compared directly with QCD phenomenology. Energy flows in both the laboratory frame and the hadronic centre of mass system and energy-energy correlations in the laboratory frame are presented. Comparing various QCD models, the colour dipole model provides the only satisfactory description of the data. In the hadronic centre of mass system the momentum components of charged particles longitudinal and transverse to the virtual boson direction are measured and compared with lower energy lepton-nucleon scattering data as well as withe+e- dat from LEP.

Abstract: We present an experimental study of theep?e?+p andep?e?+X processes using data recorded by the H1 detector in 1993 at the electron-proton collider HERA. These processes are employed to measure the luminosity with an accuracy of 4.5 %. A subsample of theep?e?+X events in which the hard photon is detected at angles ??' = 0.45 mrad with respect to the incident electron direction is used to verify experimentally the size of radiative corrections to theep?eX inclusive cross section and to investigate the structure of the proton in theQ2 domain down to 2 GeV2, lower than previously attained at HERA.

A comparison of the ρ0 cross sections with other leptoproduction experiments is presented. The ω results represent the first observation of this inclusive channel in high energy leptoproduction. The ρ0 and ω yields are found to be equal as may be expected from the available density of states in isospin space. This contrasts with spin angular momentum where the vector to pseudoscalar meson ratio is suppressed relative to the available number of spin states.

Abstract: TheW andQ2 dependence of the fragmentation functions and of the average multiplicity of charged pions is investigated, using data from the NA9 experiment at the CERN SPS on muon-proton scattering at 280 GeV. A significant increase of pion production with increasingW is observed at fixedQ2, leading to a rise of the average charged pion multiplicity, linear in lnW2, and of the pion fragmentation function in the central region, i.e. at small |xF|. This increase can be understood from the kinematic widening of the cms rapidity range proportional to lnW2 and the observedW independent height of the rapidity distribution. At fixedW, a rise of the average charged pion multiplicity withQ2 is observed. This rise appears to be weaker than that observed for all charged hadrons implying a stronger rise withQ2 for kaons and protons.

Abstract: Data are presented on exclusive ρ0 and ϕ production in deep inelastic muon scattering from a target consisting mainly of nitrogen. The ratio of the total cross sections for ρ0 and ϕ production is found to be 9∶(1.6±0.4) at 〈Q2〉=7.5 GeV2, consistent with theSU(3) prediction of 9∶2. Thet dependence for exclusive ρ0 production is found to become shallover asQ2 increases and, for largeQ2, thet dependence is typical of that for a hard scattering process. Furthermore, the ratio of the cross sections for coherent: incoherent production from nitrogen is found to decrease rapidly withQ2. Such behaviour indicates that even for exclusive vector meson production the virtual photon behaves predominantly as an electromagnetic probe.

Abstract: The Bose-Einstein correlation has been observed for pions in deep inelastic µp interactions at 280 GeV. The importance of non-interference correlations in the sample of like charge pion pairs and in the sample used for reference is discussed. The pion emission region is found to be roughly spherical in the pair rest frame with a radius of 0.46–0.84 fm and the chaos factor ? is 0.60–1.08.

Abstract: Results are presented from a study of deep inelastic 280 GeV muon-nucleon interactions on the transverse momenta and jet properties of the final state hadrons. The results are analysed in a way which attempts to separate the contributions of hard and soft QCD effects from those that arise from the fragmentation process. The fragmentation models with which the data are compared are the Lund string model, the independent jet model, the QCD parton shower model including soft gluon interference effects, and the firestring model. The discrimination between these models is discussed. Various methods of analysis of the data in terms of hard QCD processes are presented. From a study of the properties of the jet profiles a value of as, to leading order, is determined using the Lund string model, namely as=0.29±0.01 (stat.) ±0.02 (syst.), forQ2~20 GeV2.

Abstract: We present a new measurement of the total photoproduction cross section performed with the H1 detector at HERA. For an average centre of mass energy of 200 GeV a value of σtotλp=165±2±11µb has been obtained. A detailed analysis of the data in adequate kinematic regions enabled a decomposition of the total cross section in its elastic, single diffractive dissociation and remaining non-diffractive parts, based on safe assumptions on the double diffractive dissociation contribution.

Abstract: The general charge properties of the hadronic final state produced inµ+p andµ+d interactions at 280 GeV are investigated. Quark charge retention and local charge compensation is observed. The ratioF2n/F2p of the neutron to proton structure function is derived from the measurement of the average hadronic charge in µd interactions.

Abstract: A comparison is made between the properties of the final state hadrons produced in 280 GeV µp interactions and ine+e- annihilation. The Lund model of hadroproduction is used as an aid in understanding the differences observed. The hadron distributions from µp ande+e- interactions are consistent with the quark parton model assumption of environmental independence, provided that the differences in heavy quark production and hard QCD effects in the two processes are taken into account. A comparison with aK+p experiment is also made. Values are also determined for the Lund model parameters sq = 0.410 ± 0.002 ± 0.020 GeV and s' = 0.29-0.15 -0.13+0.09+0.10 GeV, controlling the transverse momenta in fragmentation and intrinsic transverse momenta of the struck quark respectively.

Abstract: New results on proton and antiproton production in the target and current fragmentation regions of high energy muon-nucleon scattering are presented. Proton and antiproton production is investigated as a function of Feynmanx and rapidity. No significant difference is observed between production on hydrogen and deuterium targets. Correlations betweenpp, and pairs are analysed and the results are compared with the predictions of the Lund fragmentation model.

Abstract: The multiplicity distributions of charged hadrons produced in the deep inelastic muon-proton scattering at 280 GeV are analysed in various rapidity intervals, as a function of the total hadronic centre of mass energy W ranging from 4–20 GeV. Multiplicity distributions for the backward and forward hemispheres are also analysed separately. The data can be well parameterized by binomial distributions, extending their range of applicability to the case of lepton-proton scattering. The energy and the rapidity dependence of the parameters is presented and a smooth transition from the negative binomial distribution via Poissonian to the ordinary binomial is observed.

Abstract: The production of strange particles has been studied in a 280 GeV muon nucleon scattering experiment with acceptance and particle identification over a large kinematical range. The data show that at large values ofxBj the interactions take place mostly on au valence quark in agreement with the basic quarkparton model predictions. This feature results in a strong forward-backward asymmetry in the distribution of strangeness along the rapidity axis. The data are compatible with a strange to non-strange quark suppression factor of ˜0.3 and with a strong suppression of strange diquarks. The distributions ofK+K- pairs show that the two kaons are preferentially produced at neighbouring values of rapidity.

Abstract: A study of the distribution of the azimuthal angle ? of charged hadrons in deep inelastic µ-p scattering is presented. The dependence of the moments of this distribution on the Feynmanx variable and the momentum transverse to the virtual photon indicates that non-zero moments arise mainly from the effects of the intrinsicKT of the struck quark with T2>>?(0.44 GeV)2, and to a lesser extent from QCD processes. No significant variation withQ2 orW2 is observed.

Abstract: Deep inelastic scattering (DIS) events, selected from 1993 data taken by the H1 experiment at HERA, are studied in the Breit frame of reference. The fragmentation function of the quark is compared with those of e+e−data. It is shown that certain aspects of the quarks emerging from within the proton in e−pinteractions are essentially the same as those of quarks pair-created from the vacuum in e+e−annihilation. The measured area, peak position and width of the fragmentation function show that the kinematic evolution variable, equivalent to the e+e−squared centre of mass energy, is in the Breit frame the invariant square of the four-momentum transfer. We comment on the extent to which we have evidence for coherence effects in pArton showers.

Abstract: Small angle scattering of 280 GeV positive muons by deuterium, carbon and calcium has been measured at scattering angles down to 2 mrad. The nucleon structure function F2extracted from deuterium does not show a significant xdependence in the measured range of Q2and its Q2dependence is linear in logQ2. For calcium, a depletion of F2is observed at low xby 30% as compared with the values at x= 0.1 where F2(Ca) and F2(D) are not significantly different. This depletion is attributed to shadowing. The carbon structure function exhibits a similar, but less pronounced, xdependence. Such behaviour is observed to be independent of Q2. The data are consistent with those obtained from other charged lepton experiments both at similar and higher values of xand Q2and considerably extend the range of the measurements down to the low values of xto be measured in forthcoming experiments at HERA.

Abstract: Properties of the hadronic final state in photoproduction events with large transverse energy are studied at the electron-proton collider HERA. Distributions of the transverse energy, jets and underlying event energy are compared todata and QCD calculations. The comparisons show that theγpevents can be consistently described by QCD models including — in addition to the primary hard scattering process — interactions between the two beam remnants. The differential jet cross sectionsdσ/dETjetanddσ/dηjetare measured.

Abstract: Correlations between charged hadrons are investigated in a 280 GeV muon-proton scattering experiment. Although most of the observed particles are decay products it is shown that the correlations found originate in the fragmentation process and are not due simply to resonance production. Correlations are demonstrated between hadrons close in rapidity with respect to their charges and to the directions of their momentum components perpendicular to the virtual photon axis. Such short range correlations are predicted by the standard hadronization models.

Abstract: The energy distribution of inclusive hadrons produced by 280 GeV muons on hydrogen and deuterium targets are compared. The sum of the scaled energy distributions of the positive and negative hadrons is found to be the same for the two targets. The difference of these distributions is observed to factorise inx andz and thez-dependence is found to be independent of the target type and have a form (1-z)2.1±0.2. The net charge of the hadronic jet is positive at highx even in the case when the scattering takes place on the neutron. These results are in good agreement with the expectations of the Quark Parton Model.
