Abstract
Neutrino-nucleus elastic scattering is reduced in dense matter because of correlations. The static structure factor for a plasma of electron s and ions is calculated from Monte Carlo simulations and parametrized with a least squares fit. Our results imply a large increase in the n eutrino mean-free path. This impacts the trapping of neutrinos in a su pernova by coherent neutral current interactions.
