Exposure-background duality in the searches of neutrinoless double beta decay

Not scheduled


Mr Manoj Kumar Singh (Institute of Physics, Academia Sinica)


Neutrinoless double-beta decay (0νββ) is an experimentally sensitive avenue to probe the Majorana-versus-Dirac nature and mass scales of neutrinos. This work [1] quantitatively explores the interplay between exposure and background levels in 0νββ experiments with respect to their target sensitivities at the design stage. In particular, background reduction will be playing increasingly important and investment-effective, if not determining, roles in future 0νββ experiments with sensitivity goals of approaching and covering the non-degenerate normal neutrino mass hierarchy. Advances in background suppression can substantially alleviate the necessity of unrealistically large exposure.
