GLUINO AND SQUARK PRODUCTION IN ASSOCIATION WITH GAUGINOS AT HADRON SUPERCOLLIDERS

We calculate production cross sections for gluinos and squarks produced in association with charginos and neutralinos at pp supercollider energies. We show that, with rather stiff cuts, a signal for giZi1 and giZi1 may be isolated from the standard-model background as well as from other super-symmetric processes; this channel may offer the best hope of a gluino mass measurement. We also estimate potential signal rates from hemispherically separated multilepton-plus-jet events that result if the chargino or neutralino decays via the purely leptonic mode. © 1990 The American Physical Society.
