The hadronic corrections to the muon anomalous magnetic moment $$a_{\mu }$$aμ, due to the gauge-invariant set of diagrams with dynamical quark loop light-by-light scattering insertions, are calculated in the framework of the nonlocal chiral quark model. These results complete calculations of all hadronic light-by-light scattering contributions to $$a_{\mu }$$aμ in the leading order in the $$1/N_{c}$$1/Nc expansion. The result for the quark loop contribution is $$a_{\mu }^{\mathrm {HLbL,Loop… 14 Citations ## Figures from this paper Light-by-Light Hadronic Corrections to the Muon G-2 Problem Within the Nonlocal Chiral Quark Model • Physics • 2017 Results of calculation of the light-by-light contribution from the lightest neutral pseudoscalar and scalar mesons and the dynamical quark loop to the muon anomalous magnetic moment are discussed in Hadronic light-by-light contribution to a μ : Extended Nambu-Jona-Lasinio, chiral quark models and chiral Lagrangians This talk discusses our old work on the hadronic light-by-light contribution to the muon anomalous magnetic moment and some more recent contributions.
