New physics effects in the rare B_s --> γ\ell^+ \ell^- decays with polarized photon

Abstract

Using the most general model independent form of the effective Hamiltonian, the rare B_s --> γ\ell^+ \ell^- decays are studied by taking into account the polarization of the photon. The total and the differential branching ratios for these decays, when photon is in the positive and negative helicity states, are presented. Dependence of these observables on the new Wilson coefficients are studied. It is also investigated the sensitivity of "photon polarization asymmetry" in B_s --> γ\ell^+ \ell^- decays to the new Wilson coefficients. It has been shown that all these physical observables are very sensitive to the existence of new physics beyond SM and their experimental measurements can give valuable information about it.
