Hadronic Antenna Patterns as a Probe of Leptoquark Production at HERA

M. Heyssler (Durham U.) · W.J. Stirling (Durham U.)

Abstract

Hadronic antenna patterns can provide a valuable diagnostic tool for probing the origin of the apparent excess of high $x, Q^{2}$ events at HERA. We present quantitative predictions for the distributions of soft particles and jets in standard deep inelastic scattering $e q \to e q$ events and in events corresponding to the production of a narrow colour-triplet scalar (`leptoquark') resonance. The corresponding distributions of soft photon radiation, which are sensitive to the leptoquark electric charge, are also presented. The distribution for one particular leptoquark assignment is shown to contain a radiation zero.
