“…This happens due to the particular properties of the neutrino oscillations in moving matter (see [4,5,8,9,12]). Thus, we conclude that in the case of the neutrinos moving in the relativistic jet of a quasar the SLν could be produced by the gravitational field, whereas there is no important contribution from interaction with matter.…”

“…For simplicity we neglect here the neutrino electric dipole moment, ǫ = 0, and also consider the case when matter is composed of only one type of fermions (electrons). The general case of ǫ = 0 and matter composed of different types of leptons is discussed in our papers mentioned above ( [6,9,10,12]). Note that n 0 = n e 1 − v 2 e in (15) and (16) is the invariant number density of matter given in the reference frame for which the total speed of matter is zero.…”

We predict a new mechanism for the spin light of neutrino (SLν) that can be emitted by a neutrino moving in gravitational fields. This effect is studied on the basis of the quasiclassical equation for the neutrino spin evolution in a gravitational field. It is shown that the gravitational field of a rotating object, in the weak-field limit, can be considered as an axial vector external field which induces the neutrino spin procession. The corresponding probability of the neutrino spin oscillations in the gravitational field has been derived for the first time. The considered in this paper SLν can be produced in the neutrino spin-flip transitions in gravitational fields. It is shown that the total power of this radiation is proportional to the neutrino gamma factor to the fourth power, and the emitted photon energy, for the case of an ultra relativistic neutrino, could span up to gamma-rays. We investigate the SLν caused by both gravitational and electromagnetic fields, also accounting for effects of arbitrary moving and polarized matter, in various astrophysical environments. In particular, we discuss the SLν emitted by a neutrino moving in the vicinity of a rotating neutron star, black hole surrounded by dense matter, as well as by a neutrino propagating in the relativistic jet from a quasar.

“…This is a rather general equation for the neutrino spin evolution that can be also used for the description of neutrino spin oscillations in different environments, such as moving and polarized matter with external electromagnetic fields (see [128] and references therein). The SLν in gravitational fields has been studied (see the second paper of [139]), for the first time, on the basis of a neutrino spin evolution equation (147).…”

(139) have been considered previously (for a review of the literature see [126][127][128][129]): i) the photon radiation by a massless neutrino (ν i → ν j + γ, i = j) due to the vacuum polarization loop diagram in the presence of an external magnetic field [130];…”

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.

An overview of neutrino electromagnetic properties, which open a door to the new physics beyond the Standard Model, is given. The effects of neutrino electromagnetic interactions both in terrestrial experiments and in astrophysical environments are discussed. The experimental bounds on neutrino electromagnetic characteristics are summarized. Future astrophysical probes of electromagnetic neutrinos are outlined.Comment: 18 pages, 2 figures, Revised version, Annalen der Physik [Ann. Phys.
