Neutrinoless Double-beta Decay With EXO: Achievements And Prospects

In this report, we discuss the latest EXO-collaboration results in the search for the 2nbb and the 0nbb decays of the Xenon, enriched to 80.67% 136Xe isotope. We will also discuss the R&D design effort and philosophy for the future ton-scale experiment, known as nEXO, in decrease background, increase energy resolution and overall detector sensitivity.
