LIMITS ON THE PRODUCTION OF SCALAR LEPTOQUARKS FROM Z(0) DECAYS AT LEP

Περίληψη:
A search has been made for pairs and for single production of scalar
leptoquarks of the first and second generations using a data sample of
392000 Z0 decays from the DELPHI detector at LEP 1. No signal was found
and limits on the leptoquark mass, production cross section and
branching ratio were set. A mass limit at 95% confidence level of 45.5
GeV/c2 was obtained for leptoquark pair production. The search for the
production of a single leptoquark probed the mass region above this
limit and its results exclude first and second generation leptoquarks D0
with masses below 65 GeV/c2 and 73 GeV/c2 respectively, at 95%
confidence level, assuming that the D0lq Yukawa coupling alpha(lambda)
is equal to the electromagnetic one. An upper limit is also given on the
coupling alpha(lambda) as a function of the leptoquark mass m(D0).
