Abstract
Preliminary results from H1 and ZEUS on e+p scattering at high momentum transfer squared, Q2, are presented, using all available data accumulated by the H1 and ZEUS experiments between 1994-97, corresponding to integrated luminosities of 37 pb-1 and 47 pb-1, respectively. The anomalies observed at high Q2 in the 1994-96 data remain, though with less significance. Since this high Q2 domain represents a new frontier in deep inelastic scattering (DIS), these data are used to search for new particles possessing direct couplings to lepton-quark pairs. Assuming that the slight excess of events observed in neutral current DIS is due to a statistical fluctuation, preliminary limits on the production of leptoquarks and of squarks in R-parity violating the minimal supersymmetric standard model are presented.
