Neutrinoless double beta decay
Some questions to guide you
- What is the importance of the dicovery of neutrinoless double beta decay?
- What does it mean to be a Majorana particle, and why is only the neutrino a candidate for being Majorana?
- What is the connection between the 0bb decay experiments and the mass hierarchy of neutrinos?
- What is the connection with lepton number violation?
- Why can only few isotopes possibly exhibit 0bb decay and why?
- What are the main experimental challenges in the experimental detection?
- What are the main technology choices ?
