Search for Leptoquarks at D0

Abstract

We present in this paper the current status of searches for leptoquarks at D0. These results include the use of next leading order theoretical predictions for the cross section for pair production of leptoquarks at hadron colliders. We also present a new optimized analysis for first generation leptoquarks with significant increase in sensitivity relative to earlier searches using D0 data. The mass limits derived from this first generation leptoquark search are relevant to the recently reported high mass events at HERA.
