TL;DR
This paper applies Quantum Field Theory to analyze how intense neutrino fluxes affect electron plasma, deriving wave dispersion relations and damping rates, with implications for supernova neutrino emissions.
Contribution
It provides a theoretical analysis of neutrino-plasma interactions using Quantum Field Theory, specifically addressing supernova conditions.
Findings
Neutrinos are not sufficiently collimated in supernovae to induce plasma instabilities.
Dispersion relations for longitudinal waves are derived.
Damping rates of plasma waves are calculated.
Abstract
Quantum Field Theory is applied to study an electron plasma under an intense neutrino flux. The dispersion relation of the longitudinal waves is derived and the damping rate is calculated. It is shown that in the case of Supernova emission the neutrinos are not collimated enough to cause plasma instabilities associated to a strong neutrino resonance effect.
