Domain wall QCD with physical quark masses

We present results for several light hadronic quantities (f_π, fK, BK, mud, mₛ, t₀1/2, w₀) 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_π, mK and m_Ω 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_π=130.2(9) MeV; fK=155.5(8) MeV; the average up/down quark mass and strange quark mass in the MS̄ scheme at 3 GeV, 2.997(49) and 81.64(1.17) MeV respectively; and the neutral kaon mixing parameter, BK, in the renormalization group invariant scheme, 0.750(15) and the MS̄ scheme at 3 GeV, 0.530(11).
