Final-sate radiation in electron-positron annihilation into a pion pair

S. Dubinsky, A. Korchin, N. Merenkov +2

The process of $e^{+} e^{-}$ annihilation into a $π^{+} π^{-}$ pair with radiation of a photon is considered. The amplitude of the reaction $e^{+} e^{-} \to π^{+} π^{-} γ$ consists of the model independe…

Vector meson dominance pion electromagnetic form factor with the sigma-model loop corrections

S. K. Dubinsky, A. Yu. Korchin, N. P. Merenkov

A model is developed for electromagnetic form factor of the pion. One-loop corrections are included in the linear sigma-model. The rho-meson contribution is added in an extended VM…
