An overview of the nEXO experiment

ORAL

Abstract

nEXO is a next-generation liquid xenon experiment to search for neutrino-less double beta decay (0νββ) of 136Xe using a monolithic 5-tonne liquid xenon time projection chamber. Ionization electrons and scintillation photons from energy deposits in liquid xenon will be recorded with a segmented anode and a large SiPM array. nEXO is designed to achieve 1% energy resolution at the 0νββ Q-value and be built with low radioactivity materials. This talk will present recent progress in the detector design and R&D, an improved modeling of signal readout, and a deep-learning-based event discrimination and data analysis architecture. These improvements result in an estimated discovery potential for 0νββ at 0.74×1028 years at 3σ significance in 10 years of data taking.
