First Measurement of Longitudinal and Transverse Muon and Proton Momentum in CC1p0π Interactions in Argon.

MicroBooNE is a short-baseline neutrino experiment located on the Booster Neutrino Beam at Fermilab. One of its primary goals is to make precise measurements of neutrino–argon interaction cross-sections, providing essential data for neutrino oscillation studies and improving interaction modelling. In this work we present the first measurement of the differential cross-sections on argon for the longitudinal and transverse momentum of muons and protons in charged-current, single-proton, zero-pion (CC1p0π) interactions, using data collected from 2015 to 2020.

By focusing on the individual momentum distributions of the particles, this analysis aims to offer deeper insights into the complexities of neutrino-nucleus interactions, enabling the testing and refinement of nuclear effect models across various energy and momentum transfer regimes. Additionally, comparisons with existing results from MINERvA and generator studies will help validate nuclear models, enhancing our understanding of kinematic scaling and its dependence on different target nuclei.

In this talk, I will present the progress made in extracting cross sections along with comparison studies to evaluate the performance and validate nuclear models.
