The renormalization group evolution of ∆B = 2 transition operators is studied at leading order in heavy quark effective theory and at next-to-leading order in QCD. We calculate new contributions that were not taken into account in previous work and obtain the complete result to next-to-leading logarithmic accuracy. The various scheme and scale dependences and their cancellation in physical quantities are discussed explicitly. The phenomenon of Bd − B̄d mixing is one of the most interesting and… CONTINUE READING
