  Squarks and gluinos have been searched for at hadron colliders in events with
multiple jets and missing transverse energy. No excess has been observed to
date, and from a comparison of experimental cross section limits and
theoretical cross section predictions one can deduce lower bounds on the squark
and gluino masses. We present an improved analysis of squark and gluino mass
bounds which is based on state-of-the-art cross section calculations including
the summation of large threshold corrections. For illustration, we consider
experimental data obtained by the CDF collaboration at the Fermilab Tevatron
and discuss the impact of the improved cross section predictions on the squark
and gluino mass limits.
