Dynamical Model for Meson Production off Nucleon and Application to Neutrino-Nucleus Reactions

TL;DR

This paper discusses the Sato-Lee model and its extensions for describing meson production in neutrino interactions with nucleons and nuclei, highlighting applications to pion production and developments in coupled-channels modeling.

Contribution

It introduces an extended dynamical model for neutrino-induced meson production and applies it to neutrino-nucleus scattering, advancing the theoretical framework for these processes.

Findings

Successful application of the SL model to neutrino-induced pion production

Extension of the model to incoherent and coherent neutrino-nucleus scattering

Development of a coupled-channels approach for excited baryon analysis

Abstract

I explain the Sato-Lee (SL) model and its extension to the neutrino-induced pion production off the nucleon. Then I discuss applications of the SL model to incoherent and coherent pion productions in the neutrino-nucleus scattering. I mention a further extension of this approach with a dynamical coupled-channels model developed in Excited Baryon Analysis Center of JLab.
