Non-Perturbative Effects of Strong Magnetic Fields on Neutrino Self-energy: A New Approach
Ferrer, E. J.
Original · EN
The Ritus' Eₚ eigenfunction method is extended to the case of spin-1 charged particles in a constant electromagnetic field and used to calculate the one-loop neutrino self-energy in the strong-field approximation mₑ²≪ eB≪ MW². The implications of the obtained results for neutrino oscillations in the early Universe, assuming the existence of a sufficiently large (mₑ²≪ eB≪ mμ²) primordial magnetic field, are discussed.
