- Аннотация: The light-by-light contribution from the lightest scalar mesons to the anomalous magnetic moment of muon is calculated in the framework of the nonlocal chiral quark model. This contribution is found to be positive as the contribution of the lightest pseudoscalar mesons. The possible crosscheck of the sign of this contribution with help of the hadronic vaccum polarization is discussed. The combined scalar–pseudoscalar contribution of lightest mesons is estimated as (6.25±0.83) · 10−10.
