Description
Neutrinoless double-beta decay (0$\nu\beta\beta$) is a key process to address some of the major outstanding issues in particle physics, such as the lepton number conservation and the Majorana nature of the neutrino. Several efforts have taken place in the last decades in order to reach higher and higher sensitivity on its half-life. The next-generation of experiments aims at covering the Inverted-Ordering region of the neutrino mass spectrum, with sensitivities on the half-lives greater than 10$^{27}$ years. Among the exploited techniques, low-temperature calorimetry has proved to be a very promising one. CUPID (CUORE Upgrade with Particle IDentification) will search for 0$\nu\beta\beta$ decay of $^{100}$Mo and will exploit the existing cryogenic infrastructure as well as the gained experience of CUORE, at the Laboratori Nazionali del Gran Sasso in Italy. Thanks to 1596 scintillating Li$_2$MoO$_4$ crystals, enriched in $^{100}$Mo, coupled to 1710 light detectors CUPID will have a simultaneous readout of heat and light that will allow for particle identification, and thus a powerful alpha background rejection.
In our talk, we will present the current status of CUPID and outline the forthcoming steps towards the construction of the experiment.
