With or without ? Hunting for the seed of the matter-antimatter asymmetry

Abstract: (arXiv)
The 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 decay of Te using a tonne-scale cryogenic calorimeter operated at milli-kelvin temperatures. We report no evidence for decay and place a lower limit on the half-life of T 3.8 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 the infrastructure for a next-generation experiment capable of searching for decay across multiple isotopes.- calorimeter: cryogenics
