The inclusive $\bar B \to X_s \gamma$ decay rate with higher precision

We present a new and upgraded analysis of the inclusive weak radiative decay of the $B$ meson in the standard model and beyond. The ${\mathcal O}(\alpha_s)$ perturbative corrections are included in a formally complete manner. At the order $\alpha_s^2$, exact dependence on the charm quark mass is calculated for the domi...

NNLO QCD corrections to the weak radiative $B$-meson decay with exact dependence on $m_c$

The inclusive weak radiative $B$-meson decay provides important constraints on many popular extensions of the Standard Model. Some of the numerically relevant Next-to-Next-to-Leading-Order QCD corrections to its branching ratio have so far been evaluated using an interpolation in the charm quark mass between the $m_c=0...
