Description
The nondiagonal Hbs coupling within the context of an effective Yukawa sector that comprises SUL(2) x UY(1)-invariant operators of up to dimension six is studied. The recent experimental result on B → Xsγ with hard photons is employed to constrain the Hbs vertex, with which the branching ratio for the Bs → γγ decay is estimated. It is found that the Bs → γγ decay can reach a branching ratio of the order of 4 x 10-8.
