Description
With the development of fast sub-nanosecond photosensors and the increasing size of xenon-based detectors for neutrinoless double beta decay ($0\nu\beta\beta$) the time-of-flight difference between scintillation and Cherenkov light can be exploited for further background mitigation. This is especially crucial for the rejection of elastic scattering of solar neutrinos, which presents a major and irreducible background for a kilotonne-scale experiment. In this talk I will present some considerations for the light detection performance of a future kt-scale xenon detector searching for $0\nu\beta\beta$ based on fast GPU-based light simulations and the projected background rejection capabilities and resulting gain in sensitivity to $0\nu\beta\beta$ using the Cherenkov light separation technique.
