In the extended Standard Model of particle physics, each neutrino mass eigenstate is predicted to have a tiny but non-vanishing magnetic moment induced by quantum field-theoretic corrections. These QFT-induced magnetic moments depend linearly on the masses of the underlying mass eigenstates with a proportionality constant . As a consequence when neutrinos are embedded in an environment containing magnetic fields the flavour oscillations get a contribution from the induced relative phases.
