“…In Fig. 6 the (e, e ′ ) JLab data for carbon, argon and titanium [48,49] are compared with the results from RPWIA, RMF, and ED-RMF models. Although the focus of this work is on the QE response (corresponding to the peak at E ′ ≈ 2 GeV in Figs.…”

Constraints in modeling the quasielastic response in inclusive lepton-nucleus scattering

We show that the quasielastic (QE) response calculated with the SuSAv2 (superscaling approach) model, that relies on the scaling phenomenon observed in the analysis of (e, e ′ ) data and on the relativistic mean-field theory, is very similar to that from a relativistic distorted wave impulse approximation model when only the real part of the optical potentials is employed. The coincidence between the results from these two completely independent approaches, which satisfactorily agree with the inclusive data, reinforces the reliability of the quasielastic predictions stemming from both models and sets constraints for the QE response. We also study the low energy and momentum transfer region of the inclusive response by confronting the results of the relativistic mean-field model with those of the Hartree-Fock continuum random-phase approximation model, which accounts for nuclear long-range correlations. Finally, we present a comparison of our results with the recent JLab (e, e ′ ) data for argon, titanium and carbon, finding good agreement with the three data sets.

“…Lastly, we would like to acknowledge that in addition to the cross sections reported in Refs. [53,[82][83][84][85][86][87][88][89][90][91][92][93], the F 2 (x, Q 2 ) structure functions for deuteron and carbon can currently be validated against the CLAS measurements performed over a broad kinematics [94,95]. The LDMX results will complement these inclusive data, as well as provide information on (semi)exclusive cross sections.…”

We point out that the LDMX (Light Dark Matter eXperiment) detector design, conceived to search for sub-GeV dark matter, will also have very advantageous characteristics to pursue electron-nucleus scattering measurements of direct relevance to the neutrino program at DUNE and elsewhere. These characteristics include a 4-GeV electron beam, a precision tracker, electromagnetic and hadronic calorimeters with near 2π azimuthal acceptance from the forward beam axis out to ∼40 • angle, and low reconstruction energy threshold. LDMX thus could provide (semi)exclusive cross-section measurements, with detailed information about final-state electrons, pions, protons, and neutrons. We compare the predictions of two widely-used neutrino generators (genie, gibuu) in the LDMX region of acceptance to illustrate the large modeling discrepancies in electron-nucleus interactions at DUNE-like kinematics. We argue that discriminating between these predictions is well within the capabilities of the LDMX detector.

The E12-14-012 experiment performed at Jefferson Lab Hall A has collected inclusive electronscattering data for different targets at the kinematics corresponding to beam energy 2.222 GeV and scattering angle 15.54 • . Here we present a comprehensive analysis of the collected data, and perform comparisons of the double differential cross sections for inclusive scattering of electrons extracted using solid targets (aluminum, carbon, and titanium) and a closed argon-gas cell. The data cover a wide range of kinematic regimes, in which quasielastic interaction, ∆-resonance excitation, and deep-inelastic scattering contribute. The double differential cross sections are reported with high precision (∼3%) for all targets over the covered kinematic range.
