| contents | We investigate the neutrino elastic differential cross-section (NDCS) and corresponding mean free path for neutral current scattering in the dense matter of a neutron star. A wide range of observed neutron star (NS) masses is considered, including the presence of $Λ$, $Ξ^{-}$, and $Ξ^{0}$ hyperons in the heaviest stars. Their presence significantly decreases the total neutrino mean free path in the heavier stars. |
