The Higgs mediated flavor violating bottom-strange quarks transitions induced at the one-loop level by a nondiagonal Hbs coupling are studied within the context of an effective Yukawa sector that comprises SUL(2)×UY(1)-invariant operators of up to dimension-six. The most recent experimental result on B→Xsγ with hard photons is employed to constraint the Hbs vertex, which is used to estimate the branching ratio for the Bs→γγ decay. It is found that the Bs→γγ decay can reach a branching ratio of the order of 4×10−8, which is 2 orders of magnitude more stringent than the current experimental limit.
