Abstract

We calculated the Stokes parameters which characterize the polarization 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 (2HDM). It is shown that the Stokes parameter xi 3, which defines the linear 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 dependence of T- and P-odd Stokes parameter xi(1) which characterizes the linear photon polarization with polarization vector out of decay plane.
