摘要

The existing data on pseudoscalar meson transition form factors are described by the sophisticated Unitary & Analytic model and are well elaborated for pseudoscalar mesons and octet baryons. Knowing the transition form factors, are specified and the contributions of processes to the muon anomaly are evaluated with remarkably suppressed errors. Also the two-gamma decay widths of the , and pseudoscalar mesons are determined by an alternative method and compared with values given by the newest Review of Particle Physics.
