Quantum theory of neutrino spin light in dense matter

Plasma Induced Neutrino Radiative Decay Instead of Neutrino Spin Light

“…Just this situation called the "spin light of neutrino" (SLν), was first proposed and investigated in detail in an extended series of papers [9][10][11][12][13]. However, in the analysis of this effect the authors overlooked such an important phenomenon as plasma influence on the photon dispersion.…”

“…One more physical parameter, a great attention was payed to in the SLν analysis [9][10][11][12][13], was the neutrino vacuum mass m ν . As the scale of neutrino vacuum mass could not exceed essentially a few electron-volts, which is much less than typical plasmon mass scales for real astrophysical situations, see Eqs.…”

“…where the plasmon energy ω cannot be taken the vacuum one (ω = |k|), as it was done in the SLν analysis [9][10][11][12][13], but it is defined by the dispersion in plasma, ω = k 2 + m 2 γ . Performing a partial integration in Eq.…”

Neutrinos and electrons in background matter

“…Within the standard model interaction of electron neutrinos and electrons with matter composed of neutrons, the modified Dirac equations are [1,2,3,4] …”

“…For unpolarized matter f µ = G F √ 2 (n n , n n v), n n and v are, respectively, the neutron number density and overage speed. We have obtained the wave functions for neutrinos and electrons in the following form [1,2,3,4] …”
