Modeling single-pion production in neutrino interactions

This paper presents a new model for single-pion production in neutrino interactions implemented in the NuWro Monte Carlo generator. The model combines contributions from nucleon resonances and non-resonant backgrounds, providing improved predictions compared to previous versions across the full kinematic range up to deep inelastic scattering. When incorporated into NuWro's nuclear framework, accounting for initial and final state effects, the new model shows better agreement with recent accelerator neutrino experiment data on pion production.
