B_K with the Wilson Quark Action: A Non-Perturbative Resolution of Operator Mixing using Chiral Ward Identities

We propose a non-perturbative method to determine the mixing coefficients of Δt = 2 four-quark operators for the Wilson quark action using chiral Ward identities. The method is applied to calcilate B_K in quenched QCD.
