Perturbative renormalization of the ΔB = 2 four-quark operators in lattice NRQCD
Description
We present a perturbative calculation of the renormalization constants for the ΔB = 2 four-quark operators, which is needed to evaluate the bag parameters BB and BS in lattice QCD. The one-loop coefficients are calculated for the O(1/M) NRQCD heavy quark action and the O(a)-improved Wilson action for light quark. Using these coefficients, which remove O(αs/aM) error, we reanalyze our previous calculation of the bag parameters
