Hadronic light-by-light contribution to the muon anomalous magnetic moment from lattice QCD

Abstract

We report preliminary results for the hadronic light-by-light scattering contribution to the muon anomalous magnetic moment. Several ensembles using 2+1 flavors of Möbius domain-wall fermions, generated by the RBC/UKQCD collaborations, are employed to take the continuum and infinite volume limits of finite volume lattice QED+QCD. We find $a_{\mu }^{\mathrm{HLbL}}=(7.41\pm 6.33)\times 10^{-10}$
