The electromagnetic dipole operator effect on B -> Xs gamma at O(alpha_s^2)

open access: yes, 2005
The flavor-changing electromagnetic dipole operator O_7 gives the dominant contribution to the B -> Xs gamma decay rate. We calculate two-loop QCD corrections to its matrix element together with the corresponding bremsstrahlung contributions. The optical
