Simulations are made with a renormalization group improved gauge action at β=2.6 and 2.9 corresponding to a -1 ≈2 and 3 GeV. Effects due to finite fifth dimensional size N 5 and finite spatial size N σ are examined in detail. Matching to the continuum operator is made perturbatively at one loop order. We obtain B K (μ=2 GeV)=0.5746(61)(191), where the first error is statistical and the second error represents an estimate of scaling violation and O(α 2 ) errors in the renormalization factor added in quadrature, as an estimate of the continuum value in the modified minimal subtraction (MS ¯ ) scheme with naive dimensional regularization. This value is consistent, albeit somewhat small, with B K (μ=2 GeV)=0.628(42) obtained by the JLQCD Collaboration using the Kogut-Susskind quark action. Results for light quark masses are also reported.}, title = {Kaon B parameter from quenched domain-wall QCD}, volume = {64}, year = {2001} }
