Search for supersymmetric particles at CDF

Analyses of events with large unbalanced transverse energy from the 1987 and 1988-89 CDF data runs have set limits on the masses of supersymmetric squarks and gluinos. In a simple model with a stable photino as the lightest supersymmetric particle, the 1987 data with an integrated luminosity of 25.3 nb-1 have excluded at the 90% CL, squarks of mass less than 73 GeV/c2 and gluinos of mass less than 74 GeV/c2. Preliminary results from an analysis of 1 pb-1 of data from the current 1988-89 run imply that the existence of a squark of mas less than 150 GeV/c2 is unlikely. (orig.)
