Description
The nEXO Collaboration is designing a very large detector to search for neutrinoless
double beta decay of Xe$^{136}$. The nEXO detector is rooted in the
current EXO-200 program, which has reached a sensitivity for the half-life of
the decay of $1.9\times10^{25}$\,y with an exposure of 99.8 kg-y. The baseline
nEXO design assumes 5 tonnes of liquid xenon, enriched in the mass 136 isotope,
within a time projection chamber. The detector is being designed to reach a
half-life sensitivity of $>5\times10^{27}$\,y, covering the inverted neutrino
mass hierarchy, with 5 years of data. We present the nEXO detector design, the
current status of R\&D efforts, and the physics case for the experiment.
