The international project “Microcalorimeter Arrays for a  Rhenium Experiment” (MARE) aimed at the direct and calorimetric measurement of the electron neutrino mass with sub-electronvolt sensitivity. 

CUORE is an international experiment to search for the neutrinoless double beta decay of ¹³⁰Te using an array of TeO₂ low temperature detectors. The experiment is in construction at the LNGS underground laboratories.
