报告摘要:
EXO-200 is a neutrinoless double beta decay (0vBB) experiment using a time projection chamber filled with ~150kg of liquid xenon, enriched in 136Xe. The experiment, located at the Waste Isolation Pilot Plant (WIPP) near Carlsbad New Mexico, completed the data taking in 2018 that started in 2011. The last two years of data, after some hardware upgrades, resulted in improved energy resolution.  Together with improved software techniques for better background discrimination and larger statistics, the final analysis gives a half-life sensitivity well of 5.0×10^25 yr at 90% CL. This talk will present the final results from the experiment as well as the outlook of its planned successor, nEXO, with 5-tonne Xe136  and a designed half-life sensitivity close to 10^28 yr.
