Molybdenum containing scintillating bolometers for double-beta decay search (LUMINEU program)

A scintillating bolometer technology, promising to be used in a next-generation cryogenic experiment to search for neutrinoless double-beta decay, is currently under development within the LUMINEU (Luminescent Underground Molybdenum Investigation for NEU-trino mass and nature) program. The recent results about the RD of high quality large volume molybdenum containing crystal scintillators (zinc and lithium molybdates), including ones produced from 100 Mo-enriched powder, and aboveground / underground tests of cryogenic detectors based on these crystals are presented here.
