摘要：We present the final results of the RBC/UKQCD calculation of the kaon B-parameter on 2+1-
flavor domain-wall fermion lattices at a−1 = 1.73(3) GeV. We simulate on two lattice volumes of
about (1.8 fm)3 and (2.7 fm)3, with the lightest valence pion about on the large volume approximately
250 MeV. The light pion masses and our chiral fermion action allow us to compare lattice
data to NLO chiral perturbation theory, facilitating a controlled extrapolation to the physical point.
We present a final result including nonperturbative renormalization and detailed systematic errors.
Our final result is BMS
K (2 GeV) = 0.524(10)(28).
