Two milestones on the road to CUPID
The collaboration has finalised a detailed background model offering the lowest index ever obtained, and has also adopted a new technology: NTL light detectors, which are much more effective at rejecting background noise.
Neutrino oscillations have confirmed that these mysterious particles have mass, contradicting the predictions of the Standard Model.

Three new results for the CUPID collaboration in the search for neutrinoless double beta decay!
The search for double beta decay without neutrino emission (0νββ) is one of the major challenges of contemporary physics, because its observation would make a clear statement about the nature of the neutrino itself and potentially on the origin of the matter/antimatter asymmetry of our universe.

A new world leading limit for 0νββ decay set by the CUPID-Mo experiment to determine the nature of the neutrino
In its standard form, double beta decay is a process in which a nucleus decays into a different nucleus and emits two electrons and two antineutrinos (2νββ). This nuclear transition is very rare, but it was detected in several nuclei with sophisticated experiments.

Searching for rare decays: molybdenum-based crystals being tested at the Modane Underground Laboratory
The international CUPID-Mo experiment conducted by French laboratories of IN2P3, CEA/IRFU and CEA/IRAMIS has been testing the use of Molybdenum-based crystals since last April to detect double beta decay without neutrino emission.

CUPID-0 found crystal and set up
In 2018, IRFU is participating  in a publication CUPID-0: the first array of enriched scintillating bolometers for 0νββ decay investigations which reviews a first matrix of bolometers installed in the Gran Sasso laboratory in Italy, with the objective of tracking the double beta decay without neutrino emission (0νββ) that will reveal the nature of neutrinos.

A Scintillating Crystal to Study an Extremely Rare Decay
After four years of study, the Luminescent Underground Molybdenum Investigation for Neutrino mass and nature (LUMINEU) collaboration has selected lithium molybdate for the manufacture of scintillating bolometers.
