Prospects for supersymmetry at the Fermilab collider

Abstract

We compute cross sections for production of pairs of strongly interacting supersymmetric (SUSY) particles in pp¯ collisions as a function of collider energy. For a scalar-quark or gluino mass of 80 GeV, we find that the ratio of the SUSY cross section to the standard-model background increases by a factor of about 10 when √s is increased from 630 to 1600 GeV. If decays to photinos are dominant, we show that in the first 2 years of running, experiments at the Fermilab Tevatron collider should be sensitive to gluino (scalar-quark) masses up to at least $m_{g̃}$=150 GeV ($m_{q̃}$=120 GeV). We show characteristic missing-$p_T$ distributions expected if SUSY particles with such masses are produced. For SUSY particles of large mass, we stress the importance of scalar-quark and gluino decays to W and Z gauginos.
