First results on the electrocouplings of high lying N* states from N$\pi\pi$ electroproduction off protons with the CLAS detector

We extended a phenomenological model [1], that was utilized for the evaluation of resonance transition helicity amplitudes from N$\pi\pi$ electroproduction cross section data at W $<$ 1.6 GeV and $Q^2$ $<$ 0.6 GeV$^2$, to provide larger kinematic coverage. A successful description of the CLAS data [2] on nine differential N$\pi\pi$ cross sections was achieved at W $<$ 1.8 GeV and $Q^2$ $<$ 1.5 GeV$^2$. The phenomenological analysis allowed us to isolate the resonant contribution and to determine electrocouplings for states with masses above 1.6 GeV. For the first time, results for the $S_{31}(1620)$, $S_{11}(1650)$, $F_{15}(1685)$, $D_{33}(1700)$, and $P_{13}(1720)$ states were obtained from the analysis of the p$\pi^+\pi^-$ exclusive channel. \\[4pt] [1] V.
