Abstract

We report the measurements of the single and double differential cross section of muon neutrino charged-current interactions on carbon with a single positively charged pion in the final state at the T2K off-axis near detector using 5.56×1020 protons on target. The analysis uses data control samples for the background subtraction and the cross section signal, defined as a single negatively charged muon and a single positively charged pion exiting from the target nucleus, is extracted using an unfolding method. The model-dependent cross section, integrated over the T2K off-axis neutrino beam spectrum peaking at 0.6 GeV, is measured to be σ=(11.76±0.44(stat)±2.39(syst))×10−40 cm2 nucleon−1. Various differential cross sections are measured, including the first measurement of the Adler angles for single charged pion production in neutrino interactions with heavy nuclei target.11 MoreReceived 11 September 2019Revised 12 December 2019DOI:https://doi.org/10.1103/PhysRevD.101.012007Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.

Summary

Introduction

Nuclei is very relevant for current and upcoming neutrino oscillation experiments In this energy range CC1πþ has the largest neutrino interaction cross section after the CC quasielastic (CCQE) process. In T2K it constitutes a background for the νμ disappearance measurement when the charged pion is not observed and its precise knowledge is relevant for all current and planned neutrino oscillation experiments. In a nuclear target, there are multinucleon contributions and final-state interactions to which the total and differential cross sections in pion kinematic variables are sensitive. A wide range of models exists and their validation requires well-understood cross section measurements, both absolute and differential, and possibly on different nuclear targets. To allow a meaningful comparison with different phenomenological models, the measured cross section data should be as independent as possible from the models themselves
