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 τ⃗μγ branching ratio becomes close to the present experimental upper bound. We also show that the Bs–Bs mixing can be significantly different from the presently allowed range in the standard model.
