Аннотация:The hadronic corrections to the muon anomalous magnetic moment aμ, 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 aμ in the leading order of the 1/Nc expansion in quark model.
The result for the quark loop contribution is aHLbL,Loop
μ = (11.0±0.9) · 10−10, and the total result is aHLbL,NCHIQM
μ =(16.8±1.2) ·10−10.
