CUPID-0 is an array of 24 Zn82Se scintillating bolometers used to search for the 0νββ decay of 82Se. It is the first large mass 0νββ experiment exploiting a double read-out technique: the phonon signal to accurately measure particle energies and the light signal to reject the α-induced background. Its success might open the road to a next generation project of ton mass scale, CUPID. The array is in operation at Laboratori Nazionali del Gran Sasso since the beginning of 2017, in this paper we present the preliminary results obtained with an exposure of 10.45 kg· y.
