Description

Nuclear double-beta decays are a unique probe to search for new physics Beyond the Standard Model. Still-unknown particles, non-standard interactions, or the violation of fundamental symmetries would affect the decay kinematic, creating detectable and characteristic experimental signatures. In particular, the energy distribution of the electrons emitted in the decay gives an insight into the decay mechanism and has been studied in several isotopes and experiments. No deviations from the prediction of the Standard Model have been reported yet. However, several new experiments are underway or in preparation and will soon increase their sensitivity, exploring uncharted parts of the parameter space. This talk will cover phenomenological and experimental aspects related to new-physics searches in double-beta decay experiments, focusing on the testable models, the most-sensitive detection techniques, and the discovery opportunities of this field.
