# Constraining nuclear physics parameters with current and future COHERENT data

## TL;DR

This paper demonstrates how current and future COHERENT data can be used to better understand nuclear structure, especially the neutron form factor, using the deformed Shell Model for improved data fitting.

## Contribution

It introduces the use of the deformed Shell Model to analyze CE$
u$NS data, providing a more accurate fit than traditional phenomenological form factors.

## Key findings

- DSM provides a better fit to COHERENT data than Helm, Fermi, and Klein-Nystrand models.
- Future COHERENT data can significantly improve constraints on nuclear form factors.
- Analysis of upgrade scenarios shows potential for enhanced sensitivity in nuclear parameter measurements.

## Abstract

Motivated by the recent observation of coherent elastic neutrino-nucleus scattering (CE$\nu $NS) at the COHERENT experiment, our goal is to explore its potential in probing important nuclear structure parameters. We show that the recent COHERENT data offers unique opportunities to investigate the neutron nuclear form factor. Our present calculations are based on the deformed Shell Model (DSM) method which leads to a better fit of the recent CE$\nu $NS data, as compared to known phenomenological form factors such as the Helm-type, symmetrized Fermi and Klein-Nystrand. The attainable sensitivities and the prospects of improvement during the next phase of the COHERENT experiment are also considered and analyzed in the framework of two upgrade scenarios.
