Abstract

This paper reports new exclusive cross sections for ep→e′π+π-p′ using the CLAS detector at Jefferson Laboratory. These results are presented for the first time at photon virtualities 2.0GeV2<Q2<5.0GeV2 in the center-of-mass energy range 1.4 GeV <W< 2.0 GeV, which covers a large part of the nucleon resonance region. Using a model developed for the phenomenological analysis of electroproduction data, we see strong indications that the relative contributions from the resonant cross sections at W<1.74 GeV increase with Q2. These data considerably extend the kinematic reach of previous measurements. Exclusive ep→e′π+π-p′ cross section measurements are of particular importance for the extraction of resonance electrocouplings in the mass range above 1.6 GeV.
