Leptoquark production at the Tevatron
Abstract
Description
I discuss the production of leptoquarks in $p\bar{p}$ collisions at the Fermilab Tevatron. Evaluated on the basis of a recent next-to-leading order calculation, the combined D0 and CDF leptoquark searches lead to a parameter-free lower mass bound of about $\ms \simgt 240$ GeV for scalar leptoquarks or squarks decaying solely to a first generation charged lepton plus quark. These results provide very stringent constraints on any explanation of the recently observed HERA excess events in terms of new particle production.
