Reach of the Fermilab Tevatron for minimal supergravity in the region of large scalar masses
Abstract
The reach of the Fermilab Tevatron for supersymmetric matter has been calculated in the framework of the minimal supergravity model in the clean trilepton channel. Previous analyses of this channel were restricted to scalar masses m0<= 1 TeV. We extend the analysis to large values of scalar masses m0 3.5 TeV. This includes the compelling hyperbolic branch/focus point (HB/FP) region, where the superpotential μ parameter becomes small. In this region, assuming a 5σ (3σ) signal with 10 (25) fb-1 of integrated luminosity, the Tevatron reach in the trilepton channel extends up to m1/2 190 (270) GeV independent of β . This corresponds to a reach in terms of the gluino mass of m 575 (750) GeV.
