We present a perturbative calculation of the renormalization constants for the ∆B = 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 c...

Based on the AdS/CFT correspondence, string theory has given exact predictions for circular Wilson loops in U (N) N = 4 supersymmetric Yang-Mills theory to all orders in a 1/N expansion. These Wilson loops can also be derived from Random Matrix Theory. In this paper we show that the result is generically insensitive to details of the Random Matrix Theory potential. We also compute all higher k-...
