Measurements of the muon-neutrino and muon-antineutrino-induced coherent charged pion production cross sections on carbon-12 by the T2K experiment.

May 15, 2025

This paper reports the T2K measured muon-neutrino and muon-antineutrino-induced charged current coherent pion production flux-averaged cross section on carbon-12 within a restricted kinematic phase-space. The results are compatible with both the NEUT 5.4.0 Berger-Sehgal (2009) and GENIE 2.8.0 Rein-Sehgal (2007) model predictions.
