Plasmon Decay in Neutrinos
{"Image DocumentName": "Plasmon Decay in Neutrinos", "Image ImageDescription": "Propagation in vacuum: Photon massless. Can not decay into other. particles, even if they. themselves are massless. Interaction in vacuum: Massless neutrinos do. not couple to photons. May have dipole moments. or even millicharges Propagation in a medium: Photon acquires a refractive index In a non-relativistic plasma. (e.g. Sun, white dwarfs, core of red. giant before helium ignition, \u2026) behaves like a massive particle: Plasma frequency. (electron density ne) Degenerate helium core. (r = 106 g/cm3, T = 8.6 keV) Interaction in a medium: Neutrinos interact coherently with. the charged particles which. themselves couple to photons. Induces an effective charge In a degenerate plasma. (electron Fermi energy EF and. Fermi momentum pF) Degenerate helium core (and CV = 1)", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
