First results on nucleon resonance photocouplings from the γp → π+π−p reaction

We report the first experimental measurements of the nine 1-fold differential cross sections for the γp→π+π−p reaction, obtained with the CLAS detector at Jefferson Laboratory. The measurements cover the invariant mass range of the final state hadrons from 1.6 GeV <W< 2.0 GeV. For the first ti...
