34. Weak radiative $B$ decays to NNLO with full charm mass dependence (20'+4')

Matthias Steinhauser, Matthias Steinhauser (KIT)

We present next-to-next-to-leading order predictions for the decay $\bar{B}\to X_s \gamma$. Special emphasis is put on the recently completed ${\cal O}(\alpha_s^2)$ corrections to the interference of the photonic dipole operator $Q_7$ and the current-current operators $Q_1$ and $Q_2$.
We provide updated results for the branching ratio with reduced uncertainties.
