Abstract

First comprehensive data on the evolution of nucleon resonance photocouplings with photon virtuality Q2 are presented for excited proton states in the mass range from 1.4 to 2.0 GeV. N* photocouplings were determined in phenomenological analysis of CLAS data on 2 pi photo and electroproduction within the framework of the JLAB-MSU phenomenological model.
