Аннотация:We obtain predictions for a number of radiative decays B(s)→V γ, V the vector meson, which proceed through the weak-annihilation mechanism. Within the factorization approximation, we take into account the photon emission from the B-meson loop and from the vector-meson loop; the latter subprocesses were not considered in the previous analyses but are found to have sizeable impact on the B(s)→Vγ decay rate. The highest branching ratios for the weak-annihilation reactions reported here are B(B¯0s→J/ψ γ)=1.5⋅10−7 and B(B−→D¯∗−s γ)=1.7⋅10−7, the estimated accuracy of these predictions being at the level of 20%.
