Prospects of discovery for supersymmetry at the Tevatron

PDF Version Also Available for Download.

Description

We summarize a discovery potential for supersymmetric particles at the p{bar p} collider of Tevatron with center-of-mass energy {radical}s = 2 TeV and integrated luminosity {integral} L dt = 15-30 fb{sup -1}. Any direct search is kinematically limited to below 450 GeV/c{sup 2}. We, however, have a unique opportunity to test various supersymmetric scenarios by a measurement of the branching ratio for the rare decay mode B{sub s} {yields} {mu}{sup +}{mu}{sup -}. Using the background estimate in the CDF analysis of B{sub s} {yields} {mu}{sup +}{mu}{sup -} in Run I, we investigate the prospects for studying this mode in Run ... continued below

Description

We summarize a discovery potential for supersymmetric particles at the p{bar p} collider of Tevatron with center-of-mass energy {radical}s = 2 TeV and integrated luminosity {integral} L dt = 15-30 fb{sup -1}. Any direct search is kinematically limited to below 450 GeV/c{sup 2}. We, however, have a unique opportunity to test various supersymmetric scenarios by a measurement of the branching ratio for the rare decay mode B{sub s} {yields} {mu}{sup +}{mu}{sup -}. Using the background estimate in the CDF analysis of B{sub s} {yields} {mu}{sup +}{mu}{sup -} in Run I, we investigate the prospects for studying this mode in Run II. CDF would be sensitive to this decay for a branching ratio > 1.2 x 10{sup -8} with 15 fb{sup -1} (or, if a similar analysis holds for D0, > 6.5 x 10{sup -9} for the combined data). For tan {beta} > 30, the B{sub s} {yields} {mu}{sup +}{mu}{sup -} search can probe the SUSY parameter space that cannot be probed by direct production of SUSY particles at Run II. An observation of B{sub s} {yields} {mu}{sup +}{mu}{sup -} with a large branching ratio > 7(14) x 10{sup -8} (feasible with only 2 fb{sup -1}) would be sufficient to exclude the mSUGRA model for tan {beta} {le} 50(55) including other experimental constraints. For some models, the branching ratio can be large enough to be detected even for small tan {beta} and large m{sub 1/2}.
