Magnetic field effects on neutrino oscillations
Abstract
Using the exact propagators in a constant magnetic field, the neutrino self-energy has been calculated to all orders in the field strength B within the minimal extension of the Weinberg-Salam model with massive Dirac neutrinos. A neutrino dispersion relation, effective potential and effective mass have been obtained that depend on B. The consequences of this effective potential on neutrino oscillations have been explored, and resonance conditions have been obtained for magnetic fields 0 < eB ≤ 4me2, where e is the elementary charge and me is the electron mass. The oscillation length has also been obtained, showing that νe-νμ resonant oscillations in magnetic field are likely to occur in the proximity of most stars generating high magnetic fields.
