Study of the radiative decayη′→π + π − γ

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The radiative decayη′→π + π − γ has been studied with the statistics of ≃2000 events. Different ways of describingm ππ distribution are considered. It is shown that if the dominating contribution to this process is made by the decay channel η′→ργ, then the generally accepted ways of describing the ρ peak do not agree with experimental data.
