Hadronic contribution from light by light processes in (g-2) of muon in nonlocal quark model

The hadronic corrections to the muon anomalous magnetic moment α_μ, due to the full gauge-invariant set of diagrams with dynamical quark loop and intermediate pseudoscalar and scalar states light-by-light scattering insertions, are calculated in the framework of the nonlocal chiral quark model. These diagrams correspond to all hadronic light-by-light scattering contributions to α_μ in the leading order of the 1/N_c expansion in quark model. The result of the quark loop contribution is _μ^HLbL,Loop=(11.0±0.9) ·10^-10, and the total result is α_μ^HLbL,NχQM=(16.8±1.2) ·10^-10.
