Our article is devoted to the computation of two three-loop diagrams that contribute to the decay $$b \to s\gamma $$ at $$\alpha _{s}^{2}$$ order. We use differential equations for master integrals (MI) to compute these diagrams for an arbitrary c-qu

With use of numerical methods for calculation of higher-order corrections to the perturbation theory, results for the renormalization constant of the wave function of a heavy quark are obtained with allowance for contribution from c-quark loops. In c

The direct CP-asymmetry in the inclusive $B \to X_d \gamma$ and $B \to X_d e^+ e^ - $ decays is investigated in the two-Higgs doublet extension of the Standard Model (2HDM). The investigation is performed in the lowest non-vanishing order of the pert

We study the inclusive rare decay $B\to X_d+\gamma$ in the supergravity inspired Minimal Supersymmetric Standard Model and compute the CP-asymmetry in the decay rates. We show that there exist two phenomenologically acceptable sets of SUSY parameters
