Neutrino cross section and oscillation measurements depend critically on modeling of hadronic final state interactions (FSI). Often, this is one of the largest components of uncertainty in a measurement. This is because of the difficulty in modeling strong interactions in nuclei in a consistent quantum-mechanical framework. FSI models are most often validated using hadron-nucleus data which introduces further uncertainties. The alternative is to use transparency data where the hadron starts propagating from inside the nucleus and the probability of interaction is measured as a function of hadron energy. This work examines the relationship between the $\pi^+$ and proton total reaction cross section and transparency from a simulation viewpoint.

  1. Signal selection and model-independent extraction of pionless charged-current muon neutrino cross section using double-differential kinematic imbalance observables on carbon and oxygen with the T2K experiment

    hep-ex 2026-07 accept novelty 6.5

    First joint C/O double-differential νμ CC0πNp cross sections in δpT–δαT and pN–cosθμ show current generators fail to describe the data.

  2. Interaction-model dependence in calorimetric energy reconstruction methods due to non-linear material effects in modern neutrino detectors

    hep-ex 2026-07 conditional novelty 6.0

    Calorimetric neutrino energy reconstruction carries an interaction-model-dependent bias of ~7-18 MeV from Birks quenching and charge recombination, reducible to ~3.5 MeV with idealised hybrid tracking.

  3. The role of final-state interaction modeling in neutrino energy reconstruction and oscillation measurements

    hep-ex 2025-11 unverdicted novelty 5.0

    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...
