Simulation shows LArTPC blips from neutron inelastic scattering can identify neutrons and reconstruct final-state neutron direction and energy in sub-GeV neutrino interactions.
Supervised ML classification of neutrino events by interaction channel prior to energy reconstruction improves accuracy and sensitivity by 10-20% in simulated DUNE analyses while remaining robust to generator mismodeling.
Hybrid HF-CRPA calculations predict lower allowed cross sections for charged-current ν_e on 40Ar at low energies, leading to ~20% fewer events in DUNE for a galactic supernova burst than the prior MARLEY model.
