Rare radiative B-s -> tau(+) tau(-) gamma decay in the two Higgs doublet model - art. no. 034010

The radiative B-s-->tau(+)tau(-)gamma decay is investigated in the framewor k of the two Higgs doublet model. The dependence of the differential branch ing ratio on the photon energy and the branching ratio on the two Higgs dou blet model parameters m(H+) and tan beta are studied. It is shown that ther e is an enhancement in the predictions of the two Higgs doublet model compa red to the standard model case. We also observe that contributions of neutr al Higgs bosons to the decay are sizable when tan beta is large.
