BINGO is actively developing a novel suite of technologies aimed at enabling neutrino physicists to conduct a future experiment with wide sensitivity across the parameter space of neutrino mass. Specifically, the experiment seeks to explore the possibility of neutrinos being of the Majorana type, which implies being identical to their antiparticles. By employing these cutting-edge technologies, BINGO-like future experiments aim to observe neutrinoless double beta decay, a long-standing hypothesized phenomenon that has yet to be detected. Such a discovery would not only confirm the Majorana nature of neutrino mass but also determine the neutrino mass scale by measuring a specific combination of the three mass eigenvalues. Furthermore, it may shed light on the intriguing disparity between the abundance of matter and the scarcity of antimatter in the Universe.
The question BINGO is addressing stands as one of the utmost priorities in modern neutrino physics, offering the potential to revolutionize our understanding of elementary particles. The possible detection of neutrinoless double beta decay would truly be transformative.
To achieve this significant breakthrough in double beta decay research, BINGO is devising groundbreaking and innovative solutions to effectively control background noise in bolometric technology. These solutions will be rigorously tested and validated through a two-isotope demonstrator named MINI-BINGO, situated in the Modane underground laboratory. Furthermore, there is a strong possibility that all of some of these advancements will be embraced by upcoming ton-scale searches such as CUPID-1T. It is important to note that this experiment is a continuation of the current bolometric searches, including CUORE, one of the most sensitive ongoing experiments currently collecting data in the Gran Sasso underground laboratory, and CUPID, its projected successor.
