Abstract
Double- and single-differential cross sections for inclusive charged-current νμ-nucleus scattering are reported for the kinematic domain 0 to 2 GeV/c in three-momentum transfer and 0 to 2 GeV in available energy, at a mean νμ energy of 1.86 GeV. The measurements are based on an estimated 995,760 νμ charged-current (CC) interactions in the scintillator medium of the NOvA Near Detector. The subdomain populated by 2-particle-2-hole (2p2h) reactions is identified by the cross section excess relative to predictions for νμ-nucleus scattering that are constrained by a data control sample. Models for 2-particle-2-hole processes are rated by χ2 comparisons of the predicted-versus-measured νμ CC inclusive cross section over the full phase space and in the restricted subdomain. Shortfalls are observed in neutrino generator predictions obtained using the theory-based València and SuSAv2 2p2h models. © 2025 authors. Published by the American Physical Society.
