Neutrino-Oxygen CC0$\pi$ scattering in the SuSAv2-MEC model

TL;DR

This paper uses the SuSAv2-MEC model to predict neutrino-oxygen scattering cross sections, validating it against electron scattering data and recent T2K measurements, showing good agreement and exploring differences with carbon interactions.

Contribution

The paper applies the SuSAv2-MEC model to neutrino-oxygen scattering and validates it against experimental data, providing new insights into oxygen interactions relevant for neutrino physics.

Findings

Good agreement with T2K data across all kinematics

Similar results for oxygen and carbon at high energies

Differences at low energies explained by nuclear effects

Abstract

We present the predictions of the SuSAv2-MEC model for the double differential charged-current muonic neutrino (antineutrino) cross section on water for the T2K neutrino (antineutrino) beam. We validate our model by comparing with the available inclusive electron scattering data on oxygen and compare our predictions with the recent T2K $\nu_\mu$-$^{16}$O data, finding good agreement at all kinematics. We show that the results are very similar to those obtained for $\nu_\mu-^{12}$C scattering, except at low energies, and we comment on the origin of this difference. A factorized spectral function model of $^{16}$O is also included for purposes of comparison.
