Non-Fermi liquid corrections to the neutrino mean free path in dense quark matter

TL;DR

This paper investigates how non-Fermi liquid effects in dense quark matter influence neutrino transport, showing that NFL corrections decrease the neutrino mean free path and increase scattering rates.

Contribution

It provides the first detailed calculation of neutrino mean free path including non-Fermi liquid corrections in dense quark matter.

Findings

NFL corrections decrease the neutrino mean free path.

NFL effects lead to higher neutrino scattering rates.

Quantitative impact of NFL corrections on neutrino transport is established.

Abstract

We calculate the neutrino mean free path with non-Fermi liquid (NFL) corrections in quark matter from scattering and absorption processes for both degenerate and nondegenerate neutrinos. We show that the mean free path decreases due to the non-Fermi liquid corrections leading to $l_{mean}^{-1}\sim[......+ .... C_F^2\alpha_s^2\ln(m_D/T)^2]$. These reduction results in higher rate of scattering.
