Abstract: The production of transverse energy in deep inelastic scattering is measured as a function of the kinematic variables x and Q 2 using the H1 detector at the ep collider HERA. The results are compared to the different predictions based upon two alternative QCD evolution equations, namely the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) and the Balitsky-Fadin-Kuraev-Lipatov (BFKL) equations. In a pseudorapidity interval which is central in the hadronic centre of mass system between the current and the proton remnant fragmentation region the produced transverse energy increases with decreasing x for constant Q 2 . Such a behaviour can be explained with a QCD calculation based upon the BFKL ansatz. The rate of forward jets, proposed as a signature for BFKL dynamics, has been measured.

Abstract: 15 pp. (1995)., A contact interaction analysis is presented to search for new phenomena beyond the Standard Model in deep inelastic e ± p → e ± hadrons scattering. The data are collected with the H1 detector at HERA and correspond to integrated luminosities of 0.909 pb −1 and 2.947 pb −1 for electron and positron beams, respectively. The differential cross sections dσ/d Q 2 are measured in the Q 2 range between 160 GeV 2 and 20 000 GeV 2 . The absence of any significant deviation from the Standard Model prediction is used to constrain the couplings and masses of new leptoquarks and to set limits on electron-quark compositeness scales and on the radius of light quarks.

Abstract: 19 pp. (1995)., A leading order determination of the gluon density in the proton has been performed in the fractional momentum range 1.9 · 10 −3 < x g / p < 0.18 by measuring multi-jet events from boson-gluon fusion in deep-inelastic scattering with the H1 detector at the electron-proton collider HERA. This direct determination of the gluon density was performed in a kinematic region previously not accessible. The data show a considerable increase of the gluon density with decreasing fractional momenta of the gluons.

Abstract: 23 pp. (1995)., Photoproduction of 2-jet events is studied with the H1 detector at HERA. Parton cross sections are extracted from the data by an unfolding method using leading order parton-jet correlations of a QCD generator. The gluon distribution in the photon is derived in the fractional momentum range 0.04 ⩽ x γ ⩽ 1 at the average factorization scale 75 GeV 2 .

Abstract: 16 pp. (1995)., We present an experimental study of theep→eγ+p andep→eγ+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→eγ+X events in which the hard photon is detected at angles θγ′ ≤ 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.

Abstract: 19 pp. (1995)., 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 − p interactions 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: 16 pp. (1995)., We present a QCD analysis of the proton structure function F 2 measured by the H1 experiment at HERA, combined with data from previous fixed target experiments. The gluon density is extracted from the scaling violations of F 2 in the range 2 · 10 −4 < x < 3 · 10 −2 and compared with an approximate solution of the QCD evolution equations. The gluon density is found to rise steeply with decreasing x .

Abstract: 16 pp. (1995)., A measurement is presented, using data taken with the H1 detector at HERA, of the contribution of diffractive interactions to deep-inelastic electron-proton ( ep ) scattering in the kinematic range 8.5 < Q 2 < 50GeV 2 , 2.4 × 10 −4 < Bjorken- x < 0.0133, and 3.7 × 10 −4 < χ p < 0.043. The diffractive contribution to the proton structure function F 2 ( x , Q 2 ) is evaluated as a function of the appropriate deep-inelastic scattering variables χ p , Q 2 , β (= χ χ p ) using a class of deep-inelastic ep scattering events with no hadronic energy flow in an interval of pseudo-rapidity adjacent to the proton beam direction. the dependence of this contribution on χ p is measured to be χ p − n with n = 1.19 ± 0.06 (stat.) ± 0.07 (syst.) independent of β and Q 2 , which is consistent with both a diffractive interpretation and a factorisable ep diffractive cross section. A first measurement of the deep-inelastic structure of the pomeron in the form of the Q 2 and β dependences of a factorised structure function is presented. For all measured β, this structure function is observed to be consistent with scale invariance.

Abstract: 32 pp. (1995)., A measurement of the proton structure function F 2 ( x , Q 2 ) is reported for momentum transfers squared Q 2 between 4.5 GeV 2 and 1600 GeV 2 and for Bjorken x between 1.8 × 10 −14 and 0.13 using data collected by the HERA experiment H1 in 1993. It is observed that F 2 increases significantly with decreasing x , confirming our previous measurement made with one tenth of the data available in this analysis. The Q 2 dependence is approximately logarithmic over the full kinematic range covered. The subsample of deep inelastic events with a large pseudo-rapidity gap in the hadronic energy flow close to the proton remnant is used to measure the “diffractive” contribution to F 2 .

Abstract: 13 pp. (1994)., We present a study of J ψ meson production in collisions of 26.7 GeV electrons with 820 GeV protons, performed with the H1-detector at the HERA collider at DESY. The J ψ mesons are detected via their leptonic decays both to electrons and muons. Requiring exactly two particles in the detector, a cross section of σ(ep → J ψ X) = (8.8±2.0±2.2) nb is determined for 30 GeV ≤ W γp ≤ 180 GeV and Q 2 ≲ 4 GeV 2 . Using the flux of quasi-real photons with Q 2 ≲ 4 GeV 2 , a total production cross section of σ ( γp → J / ψX ) = (56±13±14) nb is derived at an average W γp =90 GeV. The distribution of the squared momentum transfer t from the proton to the J ψ can be fitted using an exponential exp(− b ∥ t ∥) below a ∥ t ∥ of 0.75 GeV 2 yielding a slope parameter of b = (4.7±1.9) GeV −2 .

Abstract: 20 pp. (1993)., A measurement of the proton structure function F2 (x, Q2) is presented with about 1000 neutral current deep inelastic scattering events for Bjorken x in the range x ⋍ 10−2– 10−4andQ2> 5GeV2. The measurement is based on an integrated luminosity of 22.5 nb−1 recorded by the H1 detector in the first year of HERA operation. The structure function F2 (x, Q2) shows a significant rise with decreasing x.

Abstract: 14 pp. (1993)., A direct search for new particles in the H1 experiment at HERA is presented for masses ranging from 35 GeV up to ∼ 250 GeV. The data sample of 24 nb−1 accumulated during the first year of operation was analysed for signatures of scalar and vector leptoquarks, leptogluons, excited electrons and excited neutrinos with flavours of the first generation. No evidence for the production of such particles was found in various possible decay channels. Rejection limits are derived.
