Description
The observation of neutrinoless double beta decay in the next generation of experiments would reveal that lepton number is violated and that neutrinos are Majorana particles. Such a discovery will have far reaching implications, shedding light on the mechanism of neutrino mass generation, and giving insight on leptogenesis scenarios for the generation of the matter-antimatter asymmetry in the Universe. Double beta decay experiments are sensitive to a variety of lepton-number-violating scenarios, so that their interpretation relies on having a general and flexible theoretical framework, and on the accurate calculation of the hadronic and nuclear input arising in different mechanisms. In this talk, I will review recent progress in the development of an Effective Field Theory approach to neutrinoless double beta decay, from the electroweak scale all the way down to the typical scales of nuclear physics.
