Abstract

We calculate the leading logarithmic QCD corrections to the decay B-s --> gamma gamma in the two Higgs doublet model with tree level flavor changing currents (modeI III) including O-7 type long distance effects. Further, we analyze the dependences of the branching ratio B(B-s --> gamma gamma) and the ratio of CP-even and CP-odd amplitude squares, R = \A(+)\(2)/\A(-)\(2), on the charged Higgs boson mass m(H+/-) and the selected model III parameters xi(U,D) including the leading logarithmic QCD corrections. It is found that the measurement of the branching ratio B(B-s --> gamma gamma) is promising to search charged Higgs effects. [S0556-2821(98)09121-8]
