Neutrino quantum kinetic equations: The collision term

Abstract

Neutrinos, produced copiously in the early universe and astrophysical sites, can be treated in kinetic transport theory, appropriately extended to include quantum effects related to spin and flavor. The paper by Blaschke and Cirigliano describes how neutrino interactions in environments containing neutrinos, charged leptons, and nuclei affect energy-transfer as well as flavor and spin decoherence.
