Rare B_s -> γν\barν decay with polarized photon and new physics effects

Abstract

Using the most general, model independent effective Hamiltonian, the rare B_s ->γν\barν decay with polarized photon is studied. The sensitivity of the branching ratio and photon polarization to the new Wilson coefficients are investigated. It is shown that these physical observables are sensitive to the vector and tensor type interactions, which would be useful in search of new physics.
