## TL;DR

This paper investigates how in-medium modifications of nucleon form factors affect neutrino scattering in dense matter, showing that such modifications decrease scattering cross sections and increase neutrino mean free paths at high densities.

## Contribution

It introduces a combined analysis using relativistic mean field and quark-meson coupling models to evaluate in-medium nucleon form factors and their impact on neutrino interactions.

## Key findings

- Neutrino scattering cross sections decrease with in-medium form factor modifications.
- Neutrino mean free paths are enhanced at high baryon densities.
- In-medium effects are significant around a few times nuclear matter density.

## Abstract

Effects of the in-medium modifications of nucleon form factors on neutrino interaction in dense matter are presented by considering both the weak and electromagnetic interactions of neutrinos with the constituents of the matter. A relativistic mean field and the quark-meson coupling models are respectively adopted for the effective nucleon mass and in-medium nucleon form factors. We calculate the cross-section of neutrino scattering as well as the neutrino mean free path. We found the cross sections of neutrino scattering in cold nuclear medium decreases when the in-medium modifications of the nucleon weak and electromagnetic form factors are taken into account.This reduction results in the enhancement of the neutrino mean free path, in particular at the baryon density of around a few times of the normal nuclear matter density.
