Charm quark mass dependence of the electromagnetic dipole operator contribution to anti-B -> X(s) gamma at O(alpha**2(s))
H. M. Asatrian, T. Ewerth, H. Gabrielyan +1
We extend existing calculations of the electromagnetic dipole operator contribution to the total decay rate and the photon energy spectrum of the decay \bar{B} -> X_sγat O(α_s^2) b…

Estimate of BR(B -> X_s gamma) at O(alpha_s^2)
M. Misiak, H. M. Asatrian, K. Bieri +14
Combining our results for various O(alpha_s^2) corrections to the weak radiative B-meson decay, we are able to present the first estimate of the branching ratio at the next-to-next…
