Sensitivity and discovery potential of the proposed nEXO experiment

Sensitivity and discovery potential of the proposed nEXO experiment: nEXO is a future 0nbb decay experiment searching for this weak process in the decay of ¹³⁶Xe. nEXO is building on the experience gained and the success of the EXO-200. As reported in Physical Review C (2018), the sensitivity of nEXO, which is anticipated to deploy 5x10³ kg of liquid xenon enriched in the isotope ¹³⁶Xe to 90%, has been investigated under demonstrated and realizable background rates. The projected sensitivity of nEXO after 10 years of operation reaches 10²⁸ years, which is an improvement of almost two orders of magnitude compared to current experiments.
