First quenched results for the matrix elements of the B(B(s)) mixing parameter in the static limit from tmQCD

We report on a non-perturbative study of the scale-dependent renormalization factors of a multiplicatively renormalizable basis of Delta B=2 parity-odd four-fermion operators in quenched lattice QCD. We also present some preliminary results of the matrix elements related to the mixing parameter of t...
