Towards (semi) exclusive cross section measurements and modelling

TL;DR

This paper investigates semi-inclusive neutrino-nucleus scattering, demonstrating its sensitivity to nuclear effects, comparing theoretical models with experimental data, and proposing new variables to better understand nuclear dynamics.

Contribution

It introduces a detailed theoretical description of semi-inclusive scattering and compares RPWIA predictions with recent experimental data, highlighting the potential for improved nuclear effect analysis.

Findings

RPWIA predictions show qualitative agreement with data

New variables enhance sensitivity to nuclear effects

Future models need to go beyond RPWIA

Abstract

Semi-inclusive neutrino-nucleus scattering, corresponding to the simultaneous detection of a lepton and one or more hadrons in the final state, is shown to be much more sensitive to nuclear effects than the inclusive process. The theoretical description of the semi-inclusive process is illustrated and some comparisons of relativistic plane wave impulse approximation (RPWIA) predictions with recent MicroBooNE, T2K and MINERvA data on argon and carbon are shown. The merit of new variables constructed to enhance particular nuclear effects is also illustrated and future developments going beyond the RPWIA approach are outlined.
