Titel: Massive neutrinos in nuclear processes

Abstract

The properties of the neutrinos have been the most important issue in particle physics, astrophysics and cosmology. More than 60 years after discovery of neutrinos we do not know their basisproperties, in particular absolute mass, CP properties, magnetic moment, nature (Dirac or Majorana), statistical properties, number of massive neutrinos etc. Neutrinos are elementary neutralparticles and participate in the weak nuclear processes. The measurement of the electron spectrumin the sigle \beta-decay of tritium and 187Re is discussed in the context of the KATRIN and MAREexperiments looking for an absolute mass of neutrinos. A possibility to detect cosmological relicneutrinos in these experiments is also addressed. After neutrino oscillations discovery, search forneutrinoless double beta decay (0\nu\beta\beta-decay) represents the new frontiers of neutrino physics, allowing in principle to fix the neutrino mass scale, the neutrino nature (the Dirac or Majorana particles)and possible CP violation effects. Many next generation 0\nu\beta\beta-decay experiments are in preparation or under consideration. In this presentation the development in the field of nuclear doublebeta decay is reviewed. A connection of the 0\nu\beta\beta-decay to neutrino oscillations and other leptonnumber violating processes is established. The light and sterile neutrino exchange mechanisms aswell as R-parity breaking mechanisms of the 0\nu\beta\beta-decay are analyzed. The problem of the reliabledetermination of the 0\nu\beta\beta-decay nuclear matrix elements is addressed. The possibility of bosonneutrino and partially boson neutrino is studied in light of the 2\nu\beta\beta-decay data. A new possibilityfor study of lepton number non-conservation is proposed, namely oscillations plus deexcitations ofneutral atoms. A phenomenological analysis of this process lead to a resonant enhancement of theneutrinoless double electron capture that has a Breit-Wigner form. Finally, the perspective of thefield of the single \beta and the double \beta-decays in the context of massive neutrinos is outlined.
