摘要：

The direct CP-violations in SU(2)(L) x SU(2)(R) x U(1) model and two-Higgs doublet extension of the standard model for b --> d gamma and b --> s gamma decays are investigated. The calculated value of CP-asymmetry for these two models and for b --> d gamma and b --> s gamma 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.
