A study of backward going $p$ and $\pi^{-}$ in $\nu_{\mu}CC$ interactions with the NOMAD detector

TL;DR

This paper investigates backward proton and pion production in muon neutrino charged-current interactions with carbon nuclei, analyzing their momentum distributions and production rates to understand the underlying mechanisms, and comparing data with theoretical models.

Contribution

It provides detailed experimental data on backward particle production and evaluates the validity of reinteraction and short-range correlation models.

Findings

Backward proton data align with short-range correlation models.

Backward pion production shows distinct momentum distribution features.

Results help clarify the mechanisms behind backward particle emission.

Abstract

Backward proton and $\pi^-$ production has been studied in $\nu_{\mu}CC$ interactions with carbon nuclei. Detailed analyses of the momentum distributions, of the production rates, and of the general features of events with a backward going particle, have been carried out in order to understand the mechanism producing these particles. The backward proton data have been compared with the predictions of the reinteraction and the short range correlation models.
