英文摘要	We present a lattice calculation of the leading order hadronic vacuum polarization contribution to the muon anomalous magnetic moment for the connected light and strange quarks, aWcon;l=sin the widely used window t0 = 0.4 fm, t1 = 1.0 fm, Delta = 0.15 fm, and also of aScon;l=s in the short distance region. We use overlap fermions on four physical-point ensembles. Two 2 + 1 flavor RBC/UKQCD ensembles use domain wall fermions and Iwasaki gauge actions at a = 0.084 and 0.114 fm, and two 2 + 1 + 1 flavor MILC ensembles use the highly improved staggered quark and Symanzik gauge actions at a = 0.088 and 0.121 fm. We have incorporated infinite volume corrections from three additional domain wall fermion ensembles at L = 4.8, 6.4, and 9.6 fm and physical pion mass. For aWcon;l, we find that our results on the two smaller lattice spacings are consistent with those using the unitary setup, but those at the two coarser lattice spacings are slightly different. Eventually, we predict aWcon;l = 206.7(1.5)(1.0) and aWcon;s = 26.8(0.1)(0.3), using linear extrapolation in a2, with systematic uncertainties estimated from the difference of the central values from the RBC/UKQCD and MILC ensembles.
