Jinping bolometric double beta decay experiment
Abstract
<p indent="0mm">Possible Majorana nature of neutrinos is new physics far beyond the Standard Model and is a key scientific question at the modern frontiers of nuclear and particle physics. Neutrinoless double beta decay (0<italic>vββ</italic>) experiment is the only viable approach to determine the Majorana property. The discovery of 0<italic>vββ</italic> will has a great impact on outstanding puzzles of neutrino absolute mass scale, violation of lepton quantum number and matter anti-matter asymmetry of the universe. Among possible technological approaches to 0<italic>vββ</italic> study, cryogenic crystal bolometer with the advantages of superior energy resolution, operational stability and background discrimination, is one of the leading detector choices for next generation of 0<italic>vββ</italic> experiments. We will briefly review the current international efforts on bolometric experiment technology development for 0<italic>vββ</italic> search, and introduce China Jinping cryogenic bolometer experiment and recent R&D progress. Perspectives on neutrinoless double beta decay search based on scintillating crystal bolometer technology at China Jinping Underground Laboratory are also discussed.</p>
