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…
