Pion-pair production on a proton by photons in the energy region of nucleon-resonance excitation

Abstract

A model is proposed for describing the production of π+π pairs by real and virtual photons on protons in the energy region of nucleon-resonance excitation. The invariant-mass distributions of the π+π and π+ p systems at the photon point are calculated. The results are compared with available experimental data.
