Abstract

Exclusive π⁺π^-p photo- and electroproduction data from CLAS have considerably extended the information on the spectrum and structure of nucleon resonances. The data from the π⁺π^-p and Nπ channels have provided results on the electrocouplings of most resonances in the mass region up to 1.8 GeV and at photon virtualities up to 5.0 GeV². The recent CLAS data on π⁺π^-p photoproduction have improved knowledge on the photocouplings of nucleon resonances in the mass range of 1.6 GeV
