Abstract
A search for scalar and vector leptoquarks coupling to first generation fermions is performed using the e+p and eâp scattering data collected by the H1 experiment between 1994 and 2000. The data correspond to a total integrated luminosity of 117pbâ1. No evidence for the direct or indirect production of such particles is found in data samples with a large transverse momentum final state electron or with large missing transverse momentum. Constraints on leptoquark models are established. For leptoquark couplings of electromagnetic strength, leptoquarks with masses up to 275-325GeV are ruled out at 95% confidence level. These limits improve and supercede earlier H1 limits based on subsamples of the data used here.
