We report our results for the bag parameter B K 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  operators is needed. Our final result, in terms of the renormalization group invariant bag parameter, is  .Received: 9 July 2004, Revised: 27 July 2004, Published online: 21 September 2004 |
