In this work we derive the expressions of the neutrino mean free path(MFP) and emissivity with non Fermi liquid corrections up to next to leading order(NLO) in degenerate quark matter. The calculation has been performed both for the absorption and scattering processes. Subsequently the role of these NLO corrections on the cooling of the neutron star has been demonstrated. The cooling curve shows moderate enhancement compared to the leading order(LO) non-Fermi liquid result. Although the overall correction to the MFP and emissivity are larger compared to the free Fermi gas, the cooling behavior does not alter significantly.

  1. Neutrino absorption in two-flavor color-superconducting quark matter

    nucl-th 2025-09 conditional novelty 7.0

    In 2SC quark matter, neutrino absorption is dominated by strange-quark capture at low temperature, and a degenerate neutrino gas at electron lepton fraction 0.1 has a mean free path of meters or less.
