Identification of nuclear effects in neutrino and antineutrino interactions on nuclei using generalized final-state correlations
In the study of neutrino and antineutrino interactions in the GeV regime, kinematic imbalances of the final-state particles have sensitivities to different nuclear effects. Previous ideas based on neutrino quasielastic interactions [Lu, et al., Phys. Rev. C 94, 015503 (2016); Furmanski and Sobczyk, Phys. Rev. C 95, 065501 (2017)] are now generalized to antineutrino quasielastic interactions, as well as neutrino and antineutrino pion productions. Measurements of these generalized final-state correlations could provide unique and direct constraints on the nuclear response inherently different for neutrinos and antineutrinos and, therefore, delineate effects that could mimic charge-parity violation in neutrino oscillations.
