LABORATORI NAZIONALI DEL GRAN SASSO In this talk, the importance of the so called "neutrinoless double beta decay" transition in the search for physics beyond the Standard Model is emphasized. The expectations for the transition rate are examined in the assumption that ordinary neutrinos have Majorana masses. We stress the relevance of cosmological measurements and discuss the uncertainties implied by nuclear physics.
Work based on the review paper Adv. High Energy Phys. 2016 (2016) 2162659.
