From Electromagnetic Neutrinos to New Electromagnetic Radiation Mechanism in Neutrino Fluxes

Spin light of relativistic electrons in neutrino fluxes

“…In this short note we continue studies of a new possible realization of the spin light mechanism of electromagnetic radiation in a dense environment that was termed the "spin light of electron" (SLe ν ) in a dense neutrino flux [14]. This phenomenon is a new mechanism of electromagnetic radiation that can be emitted by an electron in a dense flux of ultra-relativistic neutrinos.…”

“…One might expect that the predicted SLe ν mechanism can have visible consequences for different astrophysical settings, for stellar core-collapse and supernova explosion phenomenology in particular. However, as it was shown in [14], the SLe ν in a dense neutrino flux in the case of emitting electrons are at rest cannot provide important consequences for the energy balance in a supernova process. This is because in case of nonmoving electrons the emitted photon energy in the SLe ν process is very small as well as the rate of the process is also very small.…”

“…where a = Gnδ m . Comparing these expressions with the corresponding characteristics of the SLe ν in case of nonmoving electrons [14], we get that…”

“…We consider a beam of electrons moving towards the neutrino flux composed of three flavors ν e , ν µ and ν τ with number densities n i (in the laboratory rest frame) moving in the same direction. Following discussion of [14], we introduce the average value n of the neutrino number density and the parameter δ e ,…”

“…It is interesting to compare the emitted photon energies in the case of the considered here SLe ν by relativistic electrons and one produced by electrons at rest (see [14]). Taking into account that in the case of nonmoving electrons ω = Gnδ, for the photons energy ratio (in the case of electron motion against the neutrino flux propagation, θ = π) we get…”
