The double-differential quasi-elastic-like (CCQE) anti-neutrino cross section from the MINERvA experiment medium energy sample as a function of transverse (pT<\/sub>) and longitudinal (p||<\/sub>) momentum. The dark points are the data and the curves show various neutrino interactions models. <\/figcaption><\/figure>\n\n\n\n

Amit Bashyal’s thesis work on anti-neutrino quasi-elastic scattering has been published as Bashyal et. al., <\/em>“High-statistics measurement of antineutrino quasielastic-like scattering at E\u03bd<\/sub> ~ 6 GeV on a hydrocarbon target”, Phys. Rev. D 108<\/strong>, 032018<\/a> , in the August 1 issue of Physical Review D. This paper uses the full MINERvA medium-energy data sample with 635,592 candidate interactions and the improved MINERvA neutrino flux and energy scale (see Amit’s previous paper, Bashyal et. al.<\/em>, “Use of neutrino scattering events with low hadronic recoil to inform neutrino flux and detector energy scale”, 2021 JINST<\/em> 16<\/strong><\/a> ). <\/p>\n\n\n\n

Left: Measured (data points) and MINERvA Tune v1 prediction (dotted lines) of CCQE-like d\u03c3\/dQ2<\/sup>
for neutrinos (red) and antineutrinos (this measurement, black) extracted with at neutrino and antineutrinos energies \u223c6 GeV. Right: Summary of fractional uncertainties on the differential antineutrino
cross section as a function of Q2<\/sup>.<\/figcaption><\/figure>\n\n\n\n

The results for anti-neutrinos are compared to a previous measurement of neutrinos by Oregon State postdoc Mateus Carneiro<\/a> and to new interaction models. The higher beam energy and statistics allow studies of the production rate out to energy-momentum transfer-squared, Q2<\/sup>, of 2.5 GeV2<\/sup>. <\/p>\n\n\n\n

Comparisons of the cross section predicted by various tunes applied on GENIE with respect to the baseline GENIE 2.12.6 (black) as a function of Q2<\/sup> (left). MINERvA Tune v1 (blue) is the standard simulation tuned to the MINERvA low energy data. MINERvA Tune v2 (red) is MINERvA Tune v1 with non-resonant pions suppressed in the low Q2<\/sup> region. The remaining curves on the left show the effect of enabling different corrections to the base model. The plots on the right show comparisons of cross-section predictions for GENIE v3.0.6 (dotted lines) with the MINERvA tuned GENIE v2.12.6 predictions. Inner error bars represent statistical uncertainties and outer error bars represent systematic uncertainties.<\/figcaption><\/figure>\n\n\n\n

The new GENIE 3 series models do a much better job of explaining the high Q2<\/sup> dependence of the observed cross section.<\/p>\n\n\n\n
