Two-loop virtual corrections to b-> sl^+l^- in the standard model
We present the results of the O(alpha_s) two-loop virtual corrections to the differential decay width dGamma(B -> X_s l+ l-)/ds, where s is the invariant mass squared of the lepton pair. Those contributions from gluon bremsstrahlung which are needed to cancel infrared and collinear singularities...
