dc.description.abstractAbstract CUPID-Mo, located in the Laboratoire Souter rain de Modane (France), was a demonstrator for the next generation 0νββ decay experiment, CUPID. It consisted of an array of 20 enriched Li2 100MoO4 bolometers and 20 Ge light detectors and has demonstrated that the technology of scintillating bolometers with particle identification capabilities is mature. Furthermore, CUPID-Mo can inform and validate the background prediction for CUPID. In this paper, we present a detailed model of the CUPID-Mo backgrounds. This model is able to describe well the features of the experimental data and enables studies of the 2νββ decay and other processes with high precision. We also measure the radio-purity of the Li2 100MoO4 crystals which are found to be sufficient for the CUPID goals. Finally, we also obtain a background index in the region of interest of 3.7 +0.9 −0.8 (stat)+1.5 −0.7 (syst)×10−3 counts/ΔEFWHM/moliso/year, the lowest in a bolometric 0νββ decay experiment.en

jyx.fundinginformationThis work has been performed in the framework of the CUPID-1 (ANR-21-CE31-0014) and LUMINEU programs, funded by the Agence Nationale de la Recherche (ANR, France). We acknowledge also the support of the P2IO LabEx (ANR-10-LABX0038) in the framework “Investissements d’Avenir” (ANR-11-IDEX-0003-01 Project “BSM-nu”) managed by ANR, France. The help of the technical staff of the Laboratoire Souterrain de Modane and of the other participant laboratories is gratefully acknowledged. We thank the mechanical workshops of LAL (now IJCLab) for the detector holders fabrication and CEA/SPEC for their valuable contribution in the detector conception. F.A. Danevich, V.V. Kobychev, V.I. Tretyak and M.M. Zarytskyy were supported in part by the National Research Foundation of Ukraine Grant No. 2020.02/0011. A.S. Barabash, S.I. Konovalov, I.M. Makarov, V.N. Shlegel and V.I. Umatov were supported by the Russian Science Foundation under Grant No. 18-12-00003. J. Kotila is supported by Academy of Finland (Grant Nos. 314733, 320062, 345869). Additionally the work is supported by the Istituto Nazionale di Fisica Nucleare (INFN) and by the EU Horizon2020 research and innovation program under the Marie Sklodowska-Curie Grant Agreement No. 754496. This work is also based on support by the US Department of Energy (DOE) Office of Science under Contract Nos. DE-AC02-05CH11231, and by the DOE Office of Science, Office of Nuclear Physics under Contract Nos. DE-FG02-08ER41551, DE-SC0011091. This research used resources of the National Energy Research Scientific Computing Center (NERSC) and the IN2P3 Computing Centre. This work makes use of the Diana data analysis software and the background model based on JAGS, developed by the CUORICINO, CUORE, LUCIFER, and CUPID-0 Collaborations. Russian and Ukrainian scientists have given and give crucial contributions to CUPID-Mo. For this reason, the CUPID-Mo collaboration is particularly sensitive to the current situation in Ukraine. The position of the collaboration leadership on this matter, approved by majority, is expressed at https://cupid-mo.mit.edu/collaboration#statement. Majority of the work described here was completed before February 24, 2022.
