Dynamical quark loop light-by-light contribution to muon g-2 within the nonlocal chiral quark model
Abstract
The hadronic corrections to the muon anomalous magnetic moment amu, 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 amu in the leading order in the 1/Nc expansion. The result for the quark loop contribution is amuHLbL,Loop=(11.0+-0.9)*10(-10), and the total result is amuHLbL,NxQM=(16.8+-1.2)*10(-10).
