Constraints on Lepton Number Violation with the 2 tonne$\cdot$yr CUORE Dataset
Abstract
Matter-antimatter asymmetry underlines the incompleteness of the current understanding of particle physics. Neutrinoless double-beta decay () may help explain this asymmetry, while unveiling the Majorana nature of the neutrino. The CUORE experiment searches for of Te using a tonne-scale cryogenic calorimeter operated at milli-kelvin temperatures. We report no evidence of and place a lower limit on the half-life of 10~years (90\% C.I.) with over 2~tonneyear TeO exposure. The tools and techniques developed for this result and the 5 year stable operation of nearly 1000 detectors demonstrate crucial infrastructure for a future-generation experiment capable of searching for across multiple isotopes.
