SENSITIVITY OF THE STOKES PARAMETERS IN THE DECAY B-]S-GAMMA-G TO THEMODEL OF FCNC

We calculated the Stokes parameters which characterize the polarizatio n properties of the photons produced in the decay b-->s gamma g in the framework of the Standard Model (SM) and Two Higgs Doublet Model (2HD M). It is shown that the Stokes parameter xi 3, which defines the line ar photon polarization with a polarization vector in the decay plane, is very sensitive to the parameters of the above-mentioned models. The predicted values of xi(3) are large enough (in some cases it achieves the maximum possible value,xi(3)-->1). We calculated the energy depen dence of T- and P-odd Stokes parameter xi(1) which characterizes the l inear photon polarization with polarization vector out of decay plane.
