We calculate the kaon B-parameter in quenched lattice QCD at β = 6.0 using Wil-son fermions at κ = 0.154 and 0.155. We use two kinds of non-local (" smeared ") sources for quark propagators to calculate the matrix elements between states of definite momentum. The use of smeared sources yields results with much smaller errors than obtained in previous calculations with Wilson fermions. By combining results for p = (0, 0, 0) and p = (0, 0, 1), we show that one can carry out the non-perturbative… CONTINUE READING
