Fermionic corrections to the interference of the electro- and chromomagnetic dipole operators in B¯→Xsγ at O(αs2)

We calculate the virtual and bremsstrahlung fermionic corrections due to the interference of the electro- and chromomagnetic dipole operators in the inclusive B¯→Xsγ decay at O(αs2) and present analytical results for both the total decay rate and the photon energy spectrum.
