Abstract:

Over the past two years, results from the Sudbury Neutrino Observatory have solved the three-decade-old Solar Neutrino Problem by conclusively demonstrating flavour transformation in solar neutrinos. These results, when combined with other solar neutrino results and reactor anti-neutrino results from KamLAND, provide strong evidence that neutrino oscillation is the underlying mechanism for the observed flavour transformation. However, these experiments could not address the fundamental questions of the absolute mass scale of neutrinos or whether neutrinos are their own anti-particles. These neutrino properties are important for understanding the evolution of the universe, and provide the foundation for the extension of the Standard Model of elementary particles.

Majorana, a new experiment searching for neutrinoless double-beta decays in a large array of 76Ge-enriched crystals has been proposed to address these questions. In this talk, I will discuss these advances in neutrino physics with the emphasis on the physics potentials of double-beta decays.

Refreshments will be available after the talk.
