Massive neutrinos and neutrino oscillations
The theory of neutrino mixing and neutrino oscillations, as well as the properties of massive neutrinos (Dirac and Majorana), are reviewed. More specifically, the following topics are discussed in
Neutrinoless Double-Beta Decay: a Probe of Physics Beyond the Standard Model
In the Standard Model the total lepton number is conserved. Thus, neutrinoless double-beta decay, in which the total lepton number is violated by two units, is a probe of physics beyond the Standard
Z line shape
During the past few years much progress has been made in the evaluation of various effects which contribute to the line shape of the Z. Some time ago the first order in α corrections [1,2] to the Z
Majorana neutrinos, neutrino mass spectrum, CP violation and neutrinoless double beta decay. 1. The Three neutrino mixing case
Assuming three-neutrino mixing and massive Majorana neutrinos, we study the implications of the neutrino oscillation solutions of the solar and atmospheric neutrino problems and of the results of the
Four-neutrino mass spectra and the Super-Kamiokande atmospheric up-down asymmetry
In the framework of schemes with mixing of four massive neutrinos, which can accommodate the atmospheric, solar and LSND ranges of $\ensuremath{\Delta}{m}^{2}$ and contain three active neutrinos and
