Abstract：
We study thd radiative annihilation decay B0s,d→J/ψ γ in the framework of QCD factorization. we show that the nonfactorizable radiative correction at the order α_s changes the magnitude sighificantly in comparison with the leading-order result with the naive factorization in the Standard Model.Future measurements of these decays would be useful testing the factorization framework.Rare radiative decays of B mesons received considerable theoretical attention due to their special sensitivity to physics beyond the Standard Model.As an example,we consider the effects of the admixture of right-hand charge currents to the standard left-hand current.This admixture will give a significant contribrution to the decays.
