Title: Sensitivity and discovery potential of nEXO to neutrinoless double beta decay

The next-generation Enriched Xenon Observatory (nEXO) is a proposed experiment to search for neutrinoless double beta (0νββ) decay in 136Xe with a target half-life sensitivity of approximately 10 28 years using 5 × 10 3 kg of isotopically enriched liquid-xenon in a time projection chamber. This improvement of two orders of magnitude in sensitivity over current limits is obtained by a significant increase of the 136Xe mass, the monolithic and homogeneous configuration of the active medium, and the multi-parameter measurements of the interactions enabled by the time projection chamber. Furthermore, the detector concept and anticipated performance are presented based upon demonstrated realizable background rates.
