Abstract

The inclusive electron neutrino charged-current cross section is measured in the NOvA near detector using 8.02×10208.02\times10^{20} protons-on-target (POT) in the NuMI beam. The sample of GeV electron neutrino interactions is the largest analyzed to date and is limited by ≃\simeq 17% systematic rather than the ≃\simeq 7.4% statistical uncertainties. The double-differential cross section in final-state electron energy and angle is presented for the first time, together with the single-differential dependence on Q2Q^{2} (squared four-momentum transfer) and energy, in the range 1 GeV ≤Eν< \leq E_{\nu} < 6 GeV. Detailed comparisons are made to the predictions of the GENIE, GiBUU, NEUT, and NuWro neutrino event generators. The data do not strongly favor a model over the others consistently across all three cross sections measured, though some models have especially good or poor agreement in the single differential cross section vs. Q2Q^{2}.
