Sitison, Ruth S. Van de Water, and Alejandro Vaquero (Fermilab Lattice, HPQCD, and MILC Collaborations) We present results for the dominant light-quark connected contribution to the long-distance window of the hadronic vacuum polarization (HVP) contribution to the muon $g−2$ from lattice quantum chromodynamics. Specifically, with a new determination of the lattice scale on MILC’s physical-mass HISQ en… [Phys. Rev. Lett. 135, 011901] Published Tue Jul 01, 2025
