Abstract:Neutrinoless double-beta decay ($0\nu2\beta$) is a hypothetical rare nuclear transition. Its observation would provide an important insight about the nature of neutrinos (Dirac or Majorana particle) demonstrating that the lepton number is not conserved. BINGO (Bi-Isotope $0\nu2\beta$ Next Generation Observatory) aims to set the technological grounds for future bolometric $0\nu2\beta$ experiments. It is based on a dual heat-light readout, i.e. a main scintillating absorber embedding the double-beta decay isotope accompanied by a cryogenic light detector. BINGO will study two of the most promising isotopes: $^{100}$Mo embedded in Li$_2$MoO$_4$ (LMO) crystals and $^{130}$Te embedded in TeO$_2$. BINGO technology will reduce dramatically the background in the region of interest, thus boosting the discovery sensitivity of $0\nu2\beta$. The proposed solutions will have a high impact on next-generation bolometric tonne-scale experiments, like CUPID. In this contribution, we present the results obtained during the first tests performed in the framework of BINGO R&D.
