摘要：

As the search for gluinos is extended to higher masses, the gluino cascade decays through lighter gaugino species can no longer be neglected. We compare gluino-cascade-decay signatures with signatures from direct gluino decay to the lightest supersymmetric particle assumed to be massless at the Fermilab Tevatron collider, assuming mg <mq. Cascade decays yield a softer missing-pT (pT) spectrum which reduces the pT cross section by a factor of 2-3 for mg=100-150 GeV. However, new signatures characteristic of the cascade appear in the 0, 1, and 2 lepton plus jets plus pT channels. We examine these signatures and compare with dominant standard-model backgrounds. © 1990 The American Physical Society.
