We calculate perturbative renormalization constants for the ∆B=2 four-quark operators in lattice NRQCD. Continuum operators ¯ bγ µ (1−γ 5)q ¯ bγ µ (1− γ 5)q and ¯ b(1 − γ 5)q ¯ b(1 − γ 5)q, which are necessary in evaluating the mass and width differences in B 0 d(s) − ¯ B 0 d(s) systems, are matched at one-loop with corresponding lattice operators(More)
