Abstract

Flavor changing neutral current and lepton flavor violating processes are studied in the SU(5) SUSY-GUT with right-handed neutrino supermultiplets. Using input parameters motivated by neutrino oscillation, it is shown that the time-dependent CP asymmetry of b → s γ can be as large as 20%. We also show that the B_s-B_s mixing can be significantly different from the standard model prediction.
