Description
We derive the oscillation formula of Majorana neutrinos based on quantum field theory. Since the Hamiltonian under the Majorana mass term does not conserve lepton number, the eigenstates of lepton number change complexly over time. With the Bogoliubov transformation, we successfully relate the lepton number eigenstates at different times. This method enables us to understand the time evolution of lepton number induced by neutrino oscillations phenomena in terms of transition probabilities. We also present the physical picture that emerges through the Majorana mass term.
