A two-flavor neutrino Pauli model and neutrino oscillations

The Pauli model of neutrino particle was investigated to study neutrino oscillations. As the Majorana properties of a neutrino cause neutrino oscillations, neutrinos are introduced in phenomenological models using special case of Majorana schemes 'Pauli model'. The model Majorana Langarangian was used to describe a system including to types of neutrinos denoted by electron and muon types. An analog of the Zel'dovich-Konopinsky-Mahmoud scheme (ZKM) scheme consisting of two case, describing the left and right states of a particle was used. In the first case, the left states was the particles and the right states was their antiparticles, while in the second case, the right states represented particles and the left states represented antiparticles. It was observed that e- and τ-type physical neutrino can be approximately described in terms of the two-component mixing. Result shows that τ neutrino is the quasi-Dirac mixture and it can be described using the lepton charge of the ZKM.
