“…The wealth of experimental and theoretical results on muon-neutrino cross sections contrasts with the few published results on electron-neutrino cross sections. After the inclusive ν e CC total cross sections measured by the Gargamelle bubble chamber in 1978 [36], the first measurement of inclusive ν e CC differential cross sections on Carbon was performed by T2K [37]. Recently the measurement performed by MINERvA of quasielastic and quasielasticlike differential cross sections on Carbon also appeared [38].…”

We analyze charged-current electron-neutrino cross sections on Carbon. We consider two different theoretical approaches, on one hand the Continuum Random Phase Approximation (CRPA) which allows a description of giant resonances and quasielastic excitations, on the other hand the RPA-based calculations which are able to describe multinucleon emission and coherent and incoherent pion production as well as quasielastic excitations. We compare the two approaches in the genuine quasielastic channel, and find a satisfactory agreement between them at large energies while at low energies the collective giant resonances show up only in the CRPA approach. We also compare electron-neutrino cross sections with the corresponding muon-neutrino ones in order to investigate the impact of the different charged-lepton masses. Finally, restricting to the RPA-based approach we compare the sum of quasielastic, multinucleon emission, coherent and incoherent one-pion production cross sections (folded with the electron-neutrino T2K flux) with the charged-current inclusive electron-neutrino differential cross sections on Carbon measured by T2K. We find a good agreement with the data. The multinucleon component is needed in order to reproduce the T2K electron-neutrino inclusive cross sections

“…The large statistics accumulated so far and the careful strategy implemented for systematic mitigation have improved our knowledge of total and differential cross sections for ν µ andν µ in the range of interest (0.3-5 GeV) for future long-baseline and sterile neutrino experiments [11]. All these experiments are, however, designed to work in ν e appearance mode and the direct measurement of ν e interactions still relies on scarce data [12,13]. Calculations are thus based on extrapolation from ν µ results.…”

Absolute neutrino cross section measurements are presently limited by uncertainties on ν fluxes. In this paper, we propose a technique that is based on the reconstruction of large angle positrons in the decay tunnel to identify three-body semileptonic K + → e + π 0 ν e decays. This tagging facility operated in positron counting mode ("event count mode") can be employed to determine the absolute ν e flux at the neutrino detector with O(1 %) precision. Facilities operated in "event by event tag mode" i.e. tagged neutrino beams that exploit the time coincidence of the positron at source and the ν e interaction at the detector, are also discussed.

“…Thus, one needs precise ν e cross sections on the detector materials in use. And yet, because of the difficulties associated with producing few-GeV electron neutrino beams, there are very few such cross section measurements [3,4]. Furthermore, the small statistics and inclusive nature of these measurements make it challenging to use them for tuning or evaluating the models used in simulation programs.…”

The electron-neutrino charged-current quasielastic (CCQE) cross section on nuclei is an important input parameter for electron neutrino appearance oscillation experiments. Current experiments typically begin with the muon neutrino cross section and apply theoretical corrections to obtain a prediction for the electron neutrino cross section. However, at present no experimental verification of the estimates for this channel at an energy scale appropriate to such experiments exists. We present the cross sections for a CCQE-like process determined using the MINERvA detector, which are the first measurements of any exclusive reaction in few-GeV electron neutrino interactions. The result is given as differential cross-sections vs. the electron energy, electron angle, and square of the four-momentum transferred to the nucleus, Q 2 . We also compute the ratio to a muon neutrino cross-section in Q 2 from MINERvA. We find satisfactory agreement between these measurements and the predictions of the GENIE generator. We furthermore report on a photon-like background unpredicted by the generator which we interpret as neutral-coherent diffractive scattering from hydrogen.
