Latest results from NEMO-3 and commissioning status of the SuperNEMO demonstrator

Abstract

Abstract The NEMO-3 experience was dedicated to the search for neutrinoless double beta decays (0νββ) and to the precise measurements of the two neutrino double beta decays (2νββ). The detector was installed at Laboratoire Souterrain de Modane (LSM) and investigated ββ decays among seven isotopes from 2003 to 2011. Its unique approach combining a calorimetric and a tracking measurement allows to fully reconstruct the ββ event topology with a very low background level. This feature also permits original searches such as the investigation of the hypothetical quadruple beta decay (0ν4β). Its successor, SuperNEMO, is currently under construction at LSM and will extend the sensitivity of the 0νββ search. The latest results from NEMO-3 concerning the 150Nd and 116Cd isotopes are presented as well as the installation status of the first SuperNEMO module.
