Rare B-s ->gamma nu(nu)over-bar decay with polarized photon and new physics effects

Sirvanli, B
Turan, Gürsevil
Using the most general, model-independent effective Hamiltonian, the rare B-s --> gammanu(ν) over bar 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.
