dc.description.abstractAll lattice-QCD calculations of the hadronic-vacuum-polarization contribution to the muon's anomalous magnetic moment to date have been performed with degenerate up- and down-quark masses. Here we calculate directly the strong-isospin-breaking correction to a(mu)(HVP) for the first time with physical values of m(u) and m(d) and dynamical u, d, s, and c quarks, thereby removing this important source of systematic uncertainty. We obtain a relative shift to be applied to lattice-QCD results obtained with degenerate light-quark masses of delta a(mu)(HVP,) (mu not equal md) = +1.5(7)%, in agreement with estimates from phenomenology.en_US
