Radiative decays with a0(980) and f0(980) from ChPT at order p^4
S. Ivashyn, A. Korchin
A consistent description of the pi0 pi0 invariant mass distribution in the phi(1020) -> f0(980) gamma -> pi0 pi0 gamma decay and the pi0 eta in phi(1020) -> a0(980) gamma -> pi0 et…
Radiative decays with light scalar mesons and singlet-octet mixing in ChPT
S. A. Ivashyn, A. Yu. Korchin
We study different types of radiative decays involving f0(980) and a0(980) mesons within a unified ChPT-based approach at one-loop level. Light scalar resonances which are seen in…
Electromagnetic form factors of charged and neutral kaons in an extended vector-meson-dominance model
S. A. Ivashyn, A. Yu. Korchin
A model is developed for electromagnetic form factors of the charged and neutral K-mesons. The formalism is based on ChPT Lagrangians with vector mesons. The form factors, calculat…
Final-sate radiation in electron-positron annihilation into a pion pair
S. Dubinsky, A. Korchin, N. Merenkov +2
The process of annihilation into a pair with radiation of a photon is considered. The amplitude of the reaction 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…
