Dynamical quark loop light-by-light contribution to muon g-2 within the nonlocal chiral quark model

The hadronic corrections to the muon anomalous magnetic moment a(mu), 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) in the leading order in the 1/N-c expansion. The result for the quark loop contribution is a(mu)(HLbL,Loop) = (11.0 +/- 0.9) x 10(-10), and the total result is a(mu)(HLbL,N chi QM) = (16.8 +/- 1.2) x 10(-10).
