Spin light in neutrino transition between different mass states

Understand

The spin light of neutrino is considered in the process of a neutrino radiative transition between two different mass states in presence of medium.

• By this study we investigate the influence of background matter on the initial and final neutrino states in the process of massive Dirac neutrino decay due to the non-zero transition magnetic moment.
• We derive corresponding corrections to the total width of the process over the matter density in most important for applications cases.
