Abstract
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/Nc expansion.
The result for the quark loop contribution is
a\_mu^HLbL,Loop=(11.0+-0.9)*10^(-10), and the total result is
a\_mu^HLbL,NxQM=(16.8+-1.2)*10^(-10). This means, that the difference in
values of a\_mu between the standard model and the experiment is 2.4 sigma.
