Contributions of $e^+e^-\to P(S)\gamma$ processes to muon $g-2$
  The present situation on a comparison of theoretical evaluation of the muon anomalous magnetic moment with experimental one is roughly reviewed. Then by means of a recently elaborated unitary and analytic model of the meson transition form factors the contributions of $e^+e^-\to P(S) \gamma$ processes to muon $g-2$ is estimated.
