Neutrino spin-flavor oscillations in electromagnetic fields of various configurations

Abstract

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 electromagnetic field. We derive transition probabilities for different neutrino magnetic moments matrices.
