Hadronic light-by-light contribution to the muon anomaly from lattice QCD with infinite volume QED at physical pion mass

The hadronic light-by-light scattering contribution to the muon anomalous magnetic moment, & eth; g - 2 & THORN;=2, is computed in the infinite volume QED framework with lattice QCD. We report a HLbL mu 1/4 12.47 & eth;1.15 & THORN;& eth;0.95 & THORN; x 10 - 10 where the first error is statistical and the second systematic. The result is mainly based on the 2 & thorn; 1 flavor M & ouml;bius domain wall fermion ensemble with inverse lattice spacing a -1 1 / 4 1.73 GeV, lattice size L 1 / 4 5.5 fm, and m pi 1 / 4 139 MeV, generated by the RBC-UKQCD collaborations. The leading systematic error of this result comes from the lattice discretization. This result is consistent with previous determinations.
