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 gZ1 and qZ1 may be isolated from the standard-model background as well as from other supersymmetric 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
