# Inelastic Neutrino-Nucleus Interactions within the Spectral Function Formalism

## TL;DR

This paper investigates neutrino-carbon interactions across a wide energy range using a spectral function approach within the impulse approximation, providing a comprehensive analysis of different scattering processes based on a realistic nuclear ground state.

## Contribution

It introduces a novel model that consistently describes quasi-elastic, resonance, and deep inelastic scattering using a realistic spectral function for the nuclear ground state.

## Key findings

- First-time consistent modeling of all interaction types from a realistic nuclear ground state.
- Quantitative comparison of quasi-elastic, resonance, and deep inelastic contributions.
- Enhanced understanding of neutrino-nucleus interactions across a broad energy spectrum.

## Abstract

We report the results of a study of neutrino-carbon interactions at beam energies ranging between few hundreds MeV and few tens of GeV, carried out within the framework of the impulse approximation using a realistic spectral function. The contributions of quasi elastic scattering, resonance production and deep inelastic scattering---consistently obtained, for first time, from a model based on a realistic description of the nuclear ground state---are compared and analyzed.
