In this paper, we discuss the main theoretical aspects and experimental effects of neutrino electromagnetic properties. We start with a general description form factors Dirac Majorana neutrinos. Then, theory phenomenology magnetic electric dipole moments, summarizing results predictions. also charge radius radiative decay. Finally, describe spin spin-flavor precession in transverse field summarize its phenomenological applications.

Using data from the COHERENT experiment, authors put bounds on neutrino electromagnetic charge radii, including first transition radii. These results show promising prospects for current and upcoming neutrino-nucleus scattering experiments.

A new theoretical framework, based on the quantum field theory of open systems applied to neutrinos, has been developed. This framework aims describe neutrino evolution in external environment, taking into account effect decoherence. We have this approach investigate a novel mechanism for decoherence, which arises due decay lighter state and massless particle, as well inverse process absorption particle by neutrino. derived generalized Lindblad master equation that accounts transitions...

We consider the massive Dirac neutrino electric charge and magnetic moment within context of standard model supplied with an SU(2)-singlet right-handed in arbitrary ${R}_{\ensuremath{\xi}}$ gauge. Using dimensional-regularization scheme we start calculations one-loop contributions to electromagnetic vertex function exactly accounting for mass. examine decomposition function. It is found by means direct that contains only four form factors. Then derive closed integral expressions different...

The exact solution effective equation for evolution presence a field and matter obtained, which accounts four species corresponding to two different flavor states with positive negative helicities. Using most stringent astrophysical bounds putative moment, probabilities spin oscillations are...

We further develop a recently proposed new approach to the description of relativistic neutrino flavour $\nu_e^L \leftrightarrow \nu_{\mu}^L$, spin \nu_{e}^R$ and spin-flavour \nu_{\mu}^R$ oscillations in constant magnetic field that is based on use exact stationary states field. The flavour, probabilities are calculated accounting for whole set possible conversions between four states. In general, obtained expressions exhibit inherent features oscillation patterns. It shown, particular,...

The ionization of atomic electrons by scattering neutrinos is revisited. This process the one studied in experimental searches for a neutrino magnetic moment using germanium detectors. Current experiments are sensitive to energy comparable with energies, and effects electron binding should be taken into account. We find that so-called stepping approximation neutrino-impact fact exact semiclassical limit also deviations from this very small already lowest bound Coulomb states. consider...

We propose an experimental setup to observe coherent elastic neutrino-atom scattering (CE$\nu$AS) using electron antineutrinos from tritium decay and a liquid helium target. In this process with the whole atom, that has not beeen observed so far, electrons tend screen weak charge of nucleus as seen by antineutrino probe. The interference between cloud produces sharp dip in recoil spectrum at atomic energies about 9 meV, reducing sizeably number expected events respect neutrino-nucleus case....

We develop the quantum theory of spin light neutrino (SLν) exactly accounting for effect background matter. Contrary to already performed studies SLν, in this Letter we derive expressions SLν rate and power emitted photon energy, which are valid an arbitrary matter density (including very high values). The spatial distribution radiation dependence energy on direction also studied detail first time. analyze polarization properties show that within a wide range momenta densities is circularly...

A short review on electromagnetic properties of neutrinos is presented. In spite many efforts in the theoretical and experimental studies neutrino properties, they still remain one main puzzles related to neutrinos.

After a brief history of two known types neutrino mixing and oscillations, including spin spin-flavor oscillations in the transversal magnetic field, we perform systematic study new phenomenon engendered by matter currents on bases developed quantum treatment phenomenon. Possibilities for resonance amplification these longitudinal fields are analyzed. Neutrino case nonstandard interactions neutrinos with background also considered.
