b to s transitions: where to look for SUSY

Abstract

We present a systematic study of the CP conserving and violating SUSY contributions to b to s processes in a generic MSSM, considering gluino exchange contributions. Experimental information on B to Xs gamma, B to Xs l+ l- and the Bs-Bsbar mass difference Delta Ms have been taken into account. We study the induced correlations among several observables: Delta Ms and the amount of CP violation in B to phi Ks, Bs to J/psi phi, B to Xs gamma. Our results show that b to s transitions represent a splendid opportunity to constrain different MSSM realizations and offer concrete prospects to exhibit SUSY signals at B factories and hadron colliders.
