Neutrino spin-flavor oscillations in electromagnetic fields of various configurations

We study spin-flavor oscillations of Dirac neutrinos with mixing and having non-zero matrix of magnetic moments in magnetic fields of various configurations. We discuss constant transversal and twisting magnetic fields. To describe the dynamics of Dirac neutrinos we use relativistic quantum mechanics approach based on the exact solutions to the Dirac-Pauli equation in an external electromagneti...

Neutrino oscillations in strong gravitational fields.

Neutrino oscillations in the presence of strong gravitational fields are studied. We look at very high energy neutrinos (∼1 TeV) emanating from Active Galactic Nuclei (AGN). It is observed that spin flavor resonant transitions of such neutrinos may occur in the vicinity of AGN due to gravitational effects and due to the presence of a large magnetic field (∼1 Tesla). A point to note is that matt...

Neutrino Oscillations: a source of Goldstone fields

It is proved that true Goldstone bosons develop coherent fields whenever the associated charges of the matter particles are not conserved in a macroscopic scale. The sources of the Goldstone fields are the time rates of quantum number violation. The case of neutrino flavour oscillations is studied with application to Supernovae. It is shown that if the Lepton numbers break at the Fermi scale, t...

Neutrino Spin-flavor Oscillations in Frequently Varying External Fields

We study the neutrino oscillations in presence of frequently varying external fields. The effective Hamiltonian describing the evolution of the system of the neutrinos is derived. We also examine the resonance conditions in the case of general frequently varying external fields. The neutrino spin-flavor oscillations in the combination of the constant transversal and twisting magnetic fields are...

Matter effects on neutrino oscillations in gravitational and magnetic fields

When neutrinos propagate in a background, their gravitational couplings are modified by their weak interactions with the particles in the background. In a medium that contains electrons but no muons or taons, the matter-induced gravitational couplings of neutrinos are different for the various neutrino flavors, and they must be taken into account in describing the phenomena associated with the ...
