Abstract
We present in this paper the current status of searches for leptoquarks at
DO. 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 DO
data. The mass limits derived from this first generation leptoquark search
are relevant to the recently reported high mass events at HERA.
I. INTRODUCTION
Leptoquarks are hypothetical exotic particles with both lepton and color quantum num-
bers; they are color triplet bosons with fractional charge. They are produced in pairs at
hadron colliders via strong interactions. A leptoquark will decay via an unknown coupling,
A, to a lepton and a quark. The production of leptoquark pairs in pp collisions is insensitive
to A, and we are not concerned with this coupling as long as it is greater than 10-"; other-
wise, the leptoquarks will not decay in our detector and escape detection. We assume that
leptoquarks occur in generations; this is to say that leptoquarks of one generation couple
