摘要：

A report is presented on our continued effort to elucidate the continuum limit of B-K using the quenched Kogut-Susskind quark action. By adding to our previous simulations one more point at beta = 6.65 employing a 56(3) x 96 lattice, we now confirm the expected O(a(2)) behavior of B-K with the Kogut-Susskind action. A simple continuum extrapolation quadratic in a leads to B-K(NDR, 2 GeV) = 0.598(5). As our final value of B-K in the continuum we present B-K(NDR, 2 GeV) = 0.628(42), as obtained by a fit including an alpha(<(MS)over bar>)(1/a)(2) term arising from the lattice-continuum matching with the one-loop renormalization.
