Finding gluinos at hadron colliders

In the minimal sypersymmetric model, we show that the branching ratio for a heavy gluino (M/sub g-italic-tilde/approx. >600 GeV) to decay directly into the lightest supersymmetric particle is less than 14%, independent of nearly all parameter assumptions. Thus, the traditional jets+E/sub T//sup m...

Zusammenfassung:In the minimal sypersymmetric model, we show that the branching ratio for a heavy gluino (M/sub g-italic-tilde/approx. >600 GeV) to decay directly into the lightest supersymmetric particle is less than 14%, independent of nearly all parameter assumptions. Thus, the traditional jets+E/sub T//sup miss/ signature is substantially reduced. We describe the results of a comprehensive survey of search strategies as a function of the supersymmetric parameter space, and identify those which are most promising. We consider a range of gluino masses appropriate to both existing and future colliders.
