Description

We report our results for the bag parameter BK obtained from the quenched simulations on the lattice with Wilson fermions for three values of the lattice spacing. We implemented the method by which no subtraction of the mixing with other four-fermion ΔS=2 operators is needed. Our final result, in terms of the renormalization group invariant bag parameter, is BK=0.96±0.10. (orig.)
