We discuss the leptoquark interpretation of the anomalous HERA positron-jet
events in the context of the YFS exponentiated Monte Carlo event generator
treatment of the attendant multiple photon radiative effects for both the
would-be signal and the SM background, wherein finite-pT​ photon effects are
properly taken into account and wherein infrared singularities are cancelled to
all orders in α. We show that H1 and ZEUS data are consistent with such
an interpretation for a leptoquark coupling ≲0.3gW​, mass ∼200
GeV, and width ≲2GeV. Possible future tests are proposed.Comment: 9 pages, 3 figures, Latex and bbl file
