Polarization effects in radiative decay of polarized lepton
G. I. Gakh, M. I. Konchatnij, A. Yu. Korchin +1
The polarization effects in the one-meson radiative decay of the polarized lepton, , are investigated. The inner bremsstrahlung and structural amplitudes are tak…
Two-photon form factors of the pi0, eta and eta-prime mesons in the chiral theory with resonances
Henryk Czyz, Sergiy Ivashyn, Alexandr Korchin +1
We have developed a phenomenological approach which describes very well the pi0, eta and eta-prime meson production in the two-photon interactions. The simultaneous description of…
e+e- annihilation to (pi0 pi0 gamma) and (pi0 eta gamma) as a source of information on scalar and vector mesons
S. Eidelman, S. Ivashyn, A. Korchin +2
We present a general framework for the model-independent decomposition of the fully differential cross section of the reactions e+e- -> gamma* -> (pi0 pi0 gamma) and e+e- -> gamma*…
On modeling the scalar meson dynamics with Resonance Chiral Theory
S. Ivashyn, A. Korchin
The features of the Resonance Chiral Theory (RChT) related to the description of the lightest scalar resonances, sigma, f0(980) and a0(980), are discussed. Major attention is paid…
Radiative decays with scalar mesons a0(980) and f0(980) in Resonance Chiral Theory
S. Ivashyn, A. Korchin
The phi(1020) radiative decays form a good playground for study of the low-lying a0(980) and f0(980) scalar mesons. The complicated interplay of kaon loop mechanism, isoscalar meso…
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…
