摘要：

A search has been made with the upgraded UA2 experiment at the CERN pp Collider at s=630 GeV for multi-jet events with large transverse momentum imbalance in a data sample corresponding to an integrated luminosity of 7.4 pb-1. Under the assumption that the photino is the lightest stable supersymmetric (SUSY) particle, the data have been used to deduce lower limits in a minimal SUSY model for the squark (mq) and the gluino (mg) masses. The 90% CL bounds are mg> 74 GeV independent of mg, mg> 79 GeV independent of mg, and and m> 106 GeV for mq=mq=m. © 1990.
