AbstraktAbstract

A new Quantum Field Theory formalism for neutrino oscillations is introduced. It identifies charged-current vertices with neutrino emission and detection, including neutrino propagation. A master formula for the charged lepton production rate, that works for both (anti)neutrino-(anti)neutrino and neutrino-antineutrino oscillations (and vice versa) in a macroscopic distance L, is presented. A relationship between Majorana masses associated with neutrino-antineutrino oscillations and neutrinoless double-beta decay is addressed. The potential of using the flux of reactor antineutrinos to observe antineutrino-neutrino oscillations is discussed. Further, an approach has been developed to construct amplitudes of processes related to neutrinos in terms of the neutrino mass matrix without reference to the neutrino mixing matrix. It is assumed that fitting experimental data in terms of the neutrino mass matrix can provide better statistical accuracy in determining the neutrino mass matrix compared to methods using the neutrino mixing matrix at intermediate stages.
