Abstract：
Recent results on nucleon resonance studies in π⁺π^－p electro- production off protons with the CLAS detector are presented. The analysis of CLAS data allowed us to determine all essential contributing mechanisms, providing a credible separation between resonant and non-resonant parts of the cross sections in a wide kinematical area of invariant masses of the final hadronic system 1.32<1.5 GeV². Electrocouplings of several excited proton states with masses less than 1.8 GeV were obtained for the first time from the analysis of π⁺π^－p exclusive electroproduction channel.
