Title: Measurements of the γ v p p ' π + π - cross section with the CLAS detector for 0.4 GeV 2 < Q 2 < 1.0 GeV 2 and 1.3 GeV < W < 1.825 GeV

Abstract

New results on the single-differential and fully-integrated cross sections for the process $$\gamma_{v} p \rightarrow p' \pi^{+} \pi^{-}$$ are presented. The experimental data were collected with the CLAS detector at Jefferson Laboratory. Measurements were carried out in the kinematic region of the reaction invariant mass $W$ from 1.3 to 1.825 GeV and the photon virtuality $Q^2$ from 0.4 to 1.0~GeV$^2$. The cross sections were obtained in narrow $$Q^{2}$$ bins (0.05 GeV$$^{2}$$) with the smallest statistical uncertainties achieved in double-pion electroproduction experiments to date. The results were found to be in agreement with previously available data where they overlap. A preliminary interpretation of the extracted cross sections, which was based on a phenomenological meson-baryon reaction model, revealed substantial relative contributions from nucleon resonances. The data offer promising prospects to improve knowledge on the $$Q^{2}$$ evolution of the electrocouplings of most resonances with masses up to $$\sim$$1.8~GeV.
