Abstract

An approach has been developed to describe two-pion production on proton by real and virtual photons in N* excitation region (W < 2 GeV). The mechanisms of two-pion production are considered as a superposition of tree diagrams containing s-channel N* excitations and non-resonant mechanisms. Absorptive correction effects in the initial γp and final πΔ states are evaluated using the results of πN inelastic amplitudes analysis.
