Analysis of T2K and MINERnA Semi-Inclusive nm􀀀12C Measurements

Abstract

We compare the semi-inclusive 𝜈𝜇−12 C cross-section measurements via T2K and MINER𝜈A collaborations with the predictions from the SuSAv2-MEC model implemented in the neutrino event generator GENIE and an unfactorized approach based on the relativistic distorted wave impulse approximation (RDWIA). Results, which include cross-sections as a function of the final muon and proton kinematics as well as correlations between both, show that the agreement with data obtained via the RDWIA approach—which accounts for final-state interactions—matches or improves GENIE-SuSAv2 predictions for very forward angles, where scaling violations are relevant.
