A neutrino passing through a dielectric medium with an index of refraction greater than unity can emit a single photon into the medium, and, in a related process, a neutrino passing through a conductor or semiconductor can emit a single plasmon into the medium. The rates for other processes are calculated, taking a simple electron gas as the medium for the plasmon calculation. Two forms of coupling of the neutrino to the electrons in the medium are considered: (1) the left-handed current coupling of the standard model; (2) a neutrino magnetic moment coupling. For the case of the largest magnetlc moments allowed by other considerations, the plasmon process could be on the verge of rendering solar "plasmon" electron neutrinos (with energies = 2 keV) observable. The plasmon process also has some potential in the detection and identification of neutrinos of mass > 10 keV, and large magnetic moments.PACS number(s1: 14.60. Gh,

Neutrino electromagnetic properties

The main goal of the paper is to give a short review on neutrino electromagnetic properties. In the introductory part of the paper a summary on what we really know about neutrinos is given: we discuss the basics of neutrino mass and mixing as well as the phenomenology of neutrino oscillations. This is important for the following discussion on neutrino electromagnetic properties that starts with a derivation of the neutrino electromagnetic vertex function in the most general form, that follows from the requirement of Lorentz invariance, for both the Dirac and Majorana cases. Then, the problem of the neutrino form factors definition and calculation within gauge models is considered. In particular, we discuss the neutrino electric charge form factor and charge radius, dipole magnetic and electric and anapole form factors. Available experimental constraints on neutrino electromagnetic properties are also discussed, and the recently obtained experimental limits on neutrino magnetic moments are reviewed. The most important neutrino electromagnetic processes involving a direct neutrino coupling with photons (such as neutrino radiative decay, neutrino Cherenkov radiation, spin light of neutrino and plasmon decay into neutrino-antineutrino pair in media) and neutrino resonant spin-flavor precession in a magnetic field are discussed at the end of the paper.

“…This equation with various modifications was previously used in [9][10][11][12][13][14][15][16][17][18][19][20] while studying of the neutrino dispersion relation and oscillation probabilities in matter as well as for discussion of neutrino mass generation. For some important cases equation (5) can be solved exactly.…”

We consider the matter effects on neutrinos moving in background on the basis of the corresponding quantum wave equations. Both Dirac and Majorana neutrino cases are discussed. The effects for Dirac neutrino reflection and trapping as well as neutrino-antineutrino annihilation and νν pair creation in matter at the interface between two media with different densities are considered. The spin light of neutrino in matter is also discussed.
