Title: New results from the studies of the Ν (1440) 1/2 +, Ν (1520) 3/2 , and Δ (1620) 1/2 resonances in exclusive ep → e'p'π +π electroproduction with the CLAS detector

In this study, the transition helicity amplitudes from the proton ground state to the N(1440)1/2 +, N(1520)3/2 , and Δ(1620)1/2 resonances (γvpN* electrocouplings) were determined from the analysis of nine independent onefold differential π +π p electroproduction cross sections off a proton target, taken with CLAS at photon virtualities 0.5GeV 2 < Q 2 < 1.5 GeV 2. The phenomenological reaction model employed for separation of the resonant and nonresonant contributions to this exclusive channel was further developed.
