Description
An important step towards a full Standard Model description of the inclusive B →Xsγ decay at next-to-next-to-leading order in the strong coupling is the evaluation of the missing contributions to the interference of the 4-quark operator P2 and the dipole operator P7. We present the complete result of the virtual and real corrections to this particular interference in the limit of vanishing charm quark mass. Our findings can be used to fix the boundary for the mc interpolation and thus help to significantly reduce the error of the Standard Model prediction for Br(B →Xsγ).
