Dirac and Majorana neutrinos in matter
Alexander Grigoriev, Alexander Studenikin, Alexei Ternov
Abstract
We consider the matter effects on neutrinos moving in background on the basis of the corresponding quantum wave equations. Both Dirac and Majorana neutrino cases are discussed. The effects for Dirac neutrino reflection and trapping as well as neutrino-antineutrino annihilation and νν pair creation in matter at the interface between two media with different densities are considered. The spin light of neutrino in matter is also discussed.
