摘要

We model the interaction of photons, pseudoscalars, and vector mesons within resonance chiral symmetric theory with SU(3) breaking. The couplings of the model are fitted to the experimental data. Within the developed model we predict the pseudoscalar-exchange light-by-light contributions to the muon anomalous magnetic moment aμP=(82.8±3.4)×10?11. The error covers also the model dependence within the class of models considered in this paper. The model was implemented into the Monte?Carlo event generator ekhara to simulate reactions e+e?→e+e?P, P=π0,η,η′ and into the Monte?Carlo event generator phokhara to simulate reactions e+e?→Pγ(γ).
