AbstraktAbstract
The SuperNEMO Demonstrator is a unique instrument for studying various modes of double beta decay. Its distinctiveness lies in the use of a tracking detector, which enables significant background suppression not only in the region of interest (ROI) for neutrinoless double beta decay (0νββ), but also within the continuum of two-neutrino double beta decay. The detector provides access to single-electron energies as well as to the angular correlation between the two electrons emitted in the decay. SuperNEMO aims to achieve a competitive background index of 2×10−4 counts⋅keV−1⋅kg−1⋅yr−1 in the 0νββ ROI, corresponding to a background-free sensitivity for an exposure of 17.5 kg⋅yr. This article briefly discusses several chosen decay modes accessible to the SuperNEMO Demonstrator.
