Hadronic Antenna Patterns as a Probe of Leptoquark Production at HERA [PDF]
, 1997 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
