Studies of $\pi^+\pi^-p$ electroproduction at $W$ from 1.4 to 1.8 GeV and $Q^2$ from 0.4 to 1.1 GeV$^{2}$ with CLAS

High precision data for the reaction $e p \rightarrow e'p'\pi^+\pi^-$ have been taken with the CLAS detector at Jefferson Lab covering the kinematic range in the hadronic invariant mass region 1.45 GeV $< W <$ 1.8 GeV and for photon virtualities 0.4 GeV$^2$ $< Q^2 <$ 1.1 GeV$^2$. Nine single-differential cross sections, composed of the angular distribution of all hadrons, the angular distributions given by all combinations of hadron pairs, and the invariant masses of all hadron pairs in the final state, have been measured. The data have been subjected to a phenomenological analysis using the reaction model [1,2], and the electrocouplings of several nucleon resonances in the mass range up to 1.8 GeV have been extracted. The data analysis and preliminary results of the resonance analysis study will be discussed. The kinematic coverage of earlier experiments [3,4] was extended. Special attention will be paid to the previously seen candidate state with $J^P=3/2^+$ at a mass of 1720 MeV.\\[4pt] [1] Mokeev, V.I. and others, Phys.Rev. C86 035203.\\[0pt] [2] Mokeev V.
