# New physics from COHERENT data with improved Quenching Factor

## TL;DR

This paper demonstrates that an improved quenching factor measurement for CsI[Na] enhances the precision of COHERENT experiment results, leading to tighter constraints on neutrino properties and new physics scenarios.

## Contribution

It introduces an updated quenching factor measurement and re-analyzes COHERENT data, significantly refining bounds on neutrino and new physics parameters.

## Key findings

- Reduced uncertainty in COHERENT measurements.
- Stronger constraints on neutrino magnetic moments.
- Enhanced sensitivity to non-standard interactions.

## Abstract

A recent new measurement and re-analysis of past measurements suggested an improved quenching factor value and uncertainty for CsI[Na]. This implies a measurement of the COHERENT experiment of coherent elastic neutrino-nucleus scattering that is closer to the Standard Model prediction and has less uncertainty. We illustrate the impact of this improvement by revisiting fits to the Weinberg angle, neutrino magnetic moments, neutron rms and neutrino charge radii, neutrino non-standard interactions (in particular those relevant for LMA-Dark) and new scalar as well as vector bosons. Significant improvement is observed, particularly for those scenarios coherently affecting the electroweak SM process.
