Charge-exchange reactions in the context of massive neutrinos in nuclear processes

AbstraktAbstract

Neutrinos are the most mysterious of the known particles playing an important role from the birth of the Universe until nowadays. There are many open questions about neutrinos that need both theoretical and experimental exploration. The subject of interest is the absolute mass scale, mixing, the Majorana or the Dirac nature of neutrinos, their electromagnetic properties and the possible existence of CP violation in the leptonic sector. The discoveries of neutrino oscillations have opened a new excited era in neutrino physics and represents a big step forward in our knowledge of neutrino properties. The observed small neutrino masses have profound implications for our understanding of the Universe and are now a major focus in astrophysics, particle and nuclear physics and in cosmology. In order to gain valuable information about neutrinos nuclear matrix elements associated with weak nuclear processes have to be understood and reliably determined. Although nuclear charge-exchange reactions are governed by the strong nuclear force, they are closely connected to electron-capture, single and double beta decays, which are transitions governed by the weak nuclear force. In this dissertation charge-exchange reactions are studied in the context of weak nuclear processes with massive neutrinos, both experimentally and theoretically...
