abstract
We present a phenomenological study of nuclear effects in neutrino charged-current interactions, using transverse kinematic imbalances in exclusive measurements. Novel observables with minimal dependence on neutrino energy are proposed to study quasielastic scattering, and especially resonance production. They should be able to provide direct constraints on nuclear effects in neutrino- and antineutrino-nucleus interactions.

Realistic variations in final-state interaction modeling can distort reconstructed neutrino energy spectra in DUNE-like experiments by amounts comparable to or exceeding those from changes in Δm²₃₂ or δ_CP, creating a potential degeneracy.
Neutrino interaction model uncertainties from nuclear physics details remain a dominant systematic in oscillation analyses and will require improved modeling plus near-detector constraints to reach the precision goals of next-generation experiments.
Fixing an error in GENIE's elastic hadron-nucleus scattering code reduces large distortions in transverse kinematic imbalance distributions for quasielastic neutrino events while having milder effects on other observables.
