| Abstract |
We present results of a large-scale simulation for the kaon B parameter BK in quenched lattice QCD with the Kogut-Susskind quark action. Calculating BK at 1(null)tatistical accuracy for seven values of lattice spacing in the range a≈0.24–0.04 fm on lattices up to 563×96, we verify the theoretically predicted quadratic a dependence. Strong indications are found that, with our level of accuracy, αMS̅(1/a)2 terms arising from our one-loop matching procedure have to be included in the continuum extrapolation. We present BK(NDR, 2 GeV) = 0.628(42) as our final value, where NDR indicates naive dimensional regularization.
