Non-accumulation of background-enhanced neutrino forces in proto-neutron stars
In a neutrino background, the vacuum two-neutrino exchange potential $V \propto G_F^2 /r^5$ acts as a much longer-ranged interaction, scaling as $V\sim1/r$ for a directional background. A proto-neutron star (PNS) hosts one of the densest astrophysical neutrino environments known, and naturally provides a setting in whi...
