Abstract
The effects of supersymmetric particles on flavor changing neutral current and lepton flavor violating processes are studied in supersymmetric SU(5) grand unified theory with right-handed neutrino supermultiplets. Using input parameters motivated by neutrino oscillation, it is shown that the time-dependent CP asymmetry of radiative B decay can be as large as 25% when the τ → μ γ branching ratio becomes close to the present experimental upper bound. We also show that the Bs-B̄s mixing can be significantly different from the presently allowed range in the standard model.
