Effect of cascade decays on the Fermilab Tevatron gluino and squark mass bounds

The CDF (Collider Detector Facility) collaboration has recently announced limits on the masses of squarks and gluinos assuming that they decay directly to a massless lightest supersymmetric particle (LSP). We examine how these mass limits change when realistic squark and gluino decays to all gaugino...

Zusammenfassung:The CDF (Collider Detector Facility) collaboration has recently announced limits on the masses of squarks and gluinos assuming that they decay directly to a massless lightest supersymmetric particle (LSP). We examine how these mass limits change when realistic squark and gluino decays to all gauginos are incorporated and the LSP mass is given by the minimal supergravity model. The gluino mass is diminished by 3--30 GeV as we vary the model parameters over their complete range. The squark mass limit is typically reduced by {approx lt}10 GeV if {ital m}(LSP){approx lt}20 GeV.
