SENSITIVITY OF THE ASYMMETRY OF THE POLARIZED B-QUARK RADIATIVE B-]S-GAMMA-G DECAY TO THE MODEL FCNC

The effects induced by the initial b-quark longitudinal polarization i n the rare b-->s gamma g decay in the standard (SM) and two Higgs doub let (2HDM) models are investigated. Using the structure functions form alism we calculate different asymmetries in b-->s gamma g decay in ter ms of the magnetic dipole type form factors, which describe the b-->s gamma and b-->sg transitions. It is shown that the general expressions for the structure functions are model independent; the model dependen t information is contained in the corresponding magnetic dipole form f actors. It is obtained that the inclusive asymmetry, corresponding to the detection of the photon only, is sensitive to the QCD corrections and to the choice of the FCNC model.
