Neutrino Spin and Dispersion in Magnetized Medium

الملخص EN

The full energy shift of a massive Dirac neutrino in magnetized electron-positron plasma was investigated using the Matsubara imaginary time and real time formalisms.

The neutrino dispersion in the magnetized medium was analyzed as a function of the neutrino spin and mass.

It was shown that in a superstrong magnetic field the CP-symmetric plasma contribution to the neutrino energy greatly exceeds the analogous correction in the field-free case.

The contribution of plasma to the anomalous magnetic moment of a neutrino was obtained.
