The hadronic light-by-light scattering contribution to the muon anomalous magnetic moment,
(g−2)/2, is computed in the infinite volume QED framework with lattice QCD. We report
aμHLbL=12.47(1.15)(0.95)×10−10 where the first error is statistical and the second systematic. The result is mainly based on the
2+1 flavor Möbius domain wall fermion ensemble with inverse lattice spacing
a−1=1.73 GeV, lattice size
L=5.5 fm, and
mπ=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. Published by the American Physical Society 2025
