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 ∼1.8 GeV.

Nucleon resonance contributions to unpolarized inclusive electron scattering

“…Furthermore, the data for ∆(1620)1/2 − , N (1720) 3/2 + , N (1720) 3/2 + and ∆(1700) 3/2 − cover a smaller range of Q 2 < 1.5 GeV 2 when compared to the other resonances, Q 2 < 5 GeV 2 . For these resonances, we have preliminary estimates of the central electrocoupling values [43] based on the good description of the π + π − p electroproduction data off protons from CLAS at 2.0 GeV 2 < Q 2 < 5.0 GeV 2 [58][59][60]. We give a conservative extrapolation uncertainty estimate for these resonance electrocouplings of at least 20% (when the relative error as calculated above is smaller).…”

Lepton-nucleus cross section measurements for DUNE with the LDMX detector

“…To this end, a systematic analysis of the data collected on various nuclear targets by different experiments using the CLAS detector in Hall B at Jefferson Laboratory, while not completely addressing the requirements outlined above, would be an important advance. So far, the published studies focused on specific hadronic processes with hydrogen targets [42][43][44][45][46][47][48][49]. These should already be useful for testing generator models for certain hadronic processes, such as ρ meson production through higher resonances.…”

“…15 and in Fig. 17, respectively, as representative examples [60,61,63] of a wide program at JLab [64,65,66,67,68,69,70,71,72]. For these three states advanced relativistic quark model calculations [73] and QCD calculations from DSE [74] and Light Cone sum rule [75] are available, for the first time employing QCD-based modeling of the excitation of the quark core.…”
