Neutrinoless Double Beta Decay with Slow Scintillator

A strength of water Cherenkov detectors is that the direction, quantity and isotropy of Cherenkov radiation produced in physics events encodes information about the type and direction of the particle(s) that produced it. In particular, solar neutrino events which produce electrons may be identified using the angle the electron subtends with the solar direction. If a 0\(\nu \beta \beta \) search was performed in a water Cherenkov detector, this technique could be used to reduce the \(^{8}\)B \(\nu \) ES background that limits the sensitivity of SNO+. Moreover, if the directionality and energy split of the two electrons emitted in 0\(\nu \beta \beta \) could be estimated from their Cherenkov signals, this information could be used to determine the underlying 0\(\nu \beta \beta \) mechanism. However, the relatively modest Cherenkov yield prohibits a \(^{130}\)Te 0\(\nu \beta \beta \) search in water: the \(\mathcal {O}\)(1 MeV) events of interest are poorly reconstructed or below detector threshold altogether in modern water Cherenkov detectors.
