Much ado about leptoquarks: A comprehensive analysis
We examine the phenomenological implications of a $\ensuremath{\sim}200\mathrm{GeV}$ leptoquark in light of the recent excess of events at DESY HERA. Given the relative predictions of events rates in ${e}^{+}p$ versus ${e}^{\ensuremath{-}}p,$ we demonstrate that classes of leptoquarks may be excluded, including those contained in ${\mathrm{E}}_{6}$ grand unified theory (GUT) models. …
