Light-quark connected intermediate-window contributions to the muon g − 2 hadronic vacuum polarization from lattice QCD Fermilab Lattice Collaboration HPQCD MILC Collaboration Gámiz Sánchez, María Elvira We present a lattice-QCD calculation of the light-quark connected contribution to window observables associated with the leading-order hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon, aHVP;LO μ . We employ the MILC Collaboration’s isospin-symmetric QCD gauge-field ensembles, which contain four flavors of dynamical highly improved staggered quarks with four lattice spacings between a ≈ 0.06–0.15 fm and close-to-physical quark masses. We consider several effectivefield- theory-based schemes for finite volume and other lattice corrections and combine the results via Bayesian model averaging to obtain robust estimates of the associated systematic uncertainties. After unblinding, our final results for the intermediate and “W2” windows are all;W μ ðconnÞ ¼ 206.6ð1.0Þ × 10−10 and all;W2 μ ðconnÞ ¼ 100.7ð3.2Þ × 10−10, respectively 2023-11-14T12:07:43Z 2023-11-14T12:07:43Z 2023-02-06 journal article Fermilab Lattice, H.
