A General analysis of the lepton polarizations in Bs ->γ\ell^+ \ell^- decays

Abstract

We present a general analysis of the lepton polarizations in the rare Bs ->γ\ell^+ \ell^- decays by using the most general model independent form of the effective Hamiltonian. The sensitivity of the longitudinal, transverse and normal polarizations of final state leptons, as well as lepton-antilepton combined asymmetries, on the new Wilson coefficients are investigated. It has been shown that all these physical observables are very sensitive to the existence of new physics beyond the standard model and their experimental measurements can give valuable information about it.
