Description
This talk provides a theoretical overview of neutrino-nucleus cross-section modeling, focusing on the critical role of Monte Carlo event generators. These generators serve as an indispensable bridge connecting theoretical predictions with the diverse event topologies observed in detectors across long-baseline neutrino-oscillation experiments, including T2K, HK, NOvA, SBN, MicroBooNE, and DUNE.
Typically, event generators operate within a two-step framework: an initial elementary-vertex interaction, followed by the propagation of the produced hadrons through the nuclear medium, a process conventionally managed by classical intranuclear cascade (INC) models.
In this presentation, we address the following key questions: Which nuclear effects and physical ingredients must be incorporated into the elementary-vertex model versus the INC? What experimental data can effectively benchmark and refine both stages? Finally, to what extent should the elementary-vertex and INC models be consistent, and are they truly independent?
