CP-violation in b quark radiative inclusive decays

The direct CP-violations in SU(2)L × SU(2)R × U(1) model and two-Higgs doublet extension of the standard model for b → dγ and b → sγ decays are investigated. The calculated value of CP-asymmetry for these two models and for b → dγ and b → sγ decays for the wide range of parameters may exceed the value, predicted by the standard model and has a sign opposite to that of the latter.
