Neutrino flavor conversion in a neutrino background: Single- versus multi-particle description
Neutrino flavor conversion in a neutrino background: Single- versus multi-particle description
In the early Universe, or near a supernova core, neutrino flavor evolution may be affected by coherent neutrino-neutrino scattering. We develop a microscopic picture of this phenomenon. We show that coherent scattering does not lead to the formation of entangled states in the neutrino ensemble and therefore the evolution of …
