Description
The discovery of neutrinoless double beta decay (0vbb) would firmly establish the Majorana nature of the neutrino mass and provide unequivocal evidence of lepton number non-conservation, a clear signature of physics beyond the Standard Model. The nEXO experiment is a monolithic cylindrical time projection chamber (TPC) with 5 tonnes of liquid xenon enriched to 90% in the isotope 136Xe aim to search the neutrinoless double-beta decay (0vbb) mode of 136Xe isotope. In the design, nEXO will achieve 1% energy resolution and with the deep-learning-based topological discrimination, and strong self-shielding of the inner detector volume, finally, can reach a half-life sensitivity to 0vbb excedding 10^28 years at the 90%CL. This talk provides an overview of nEXO project as well as a summary of the diverse range of R&D efforts currently underway.
