We calculate the next-to-leading QCD corrections to the effective Hamiltonian for B → Xse +e− in the NDR and HV schemes. We give for the first time analytic expressions for the Wilson Coefficient of the operator Q9 = (s̄b)V−A(ēe)V in the NDR and HV schemes. Calculating the relevant matrix elements of local operators in the spectator model we demonstrate the scheme independence of the resulting short distance contribution to the physical amplitude. Keeping consistently only leading and next-to… CONTINUE READING
