Domain wall QCD with physical quark masses

We present results for several light hadronic quantities (f(pi), f(K), B-K, m(ud), m(s), t(0)(1/2), w(0)) obtained from simulations of 2 + 1 flavor domain wall lattice QCD with large physical volumes and nearly physical pion masses at two lattice spacings. We perform a short, O(3)%, extrapolation in pion mass to the physical values by combining our new data in a simultaneous chiral/continuum global fit with a number of other ensembles with heavier pion masses. We use the physical values of m(pi), m(K) and m(Omega) to determine the two quark masses and the scale-all other quantities are outputs from our simulations. We obtain results with subpercent statistical errors and negligible chiral and finite-volume systematics for these light hadronic quantities, including f(pi) = 130.2(9) MeV; f(K) = 155.5(8) MeV; the average up/down quark mass and strange quark mass in the (MS) over bar scheme at 3 GeV, 2.997(49) and 81.64(1.17) MeV respectively; and the neutral kaon mixing parameter, B-K, in the renormalization group invariant scheme, 0.750(15) and the (MS) over bar scheme at 3 GeV, 0.530(11).
