Аннотация:The light-by-light contribution from the axial-vector (AV) mesons
exchanges to the muon anomalous magnetic moment is estimated in the framework
of the nonlocal chiral quark model. The preliminary answer for contributions
from a1 and f1 mesons to (g-2)mu is 0:34 10-11 and does not support the
Melnikov-Vainshtein estimate 2.2 10-11.
