Abstract
The Neutrino Experiment with a Xenon TPC (NEXT) searches for the neutrinoless double beta ($0\nu\beta\beta$) of $^{136}$Xe using high-pressure xenon gas TPCs with electroluminescent amplification. A scaled-up version of this technology with $\sim1$tonne of enriched xenon could reach, in a few years of operation, a sensitivity to the half-life of $0\nu\beta\beta$ decay better than $10^{27}$years, improving the current limits by at least one order of magnitude. This prediction is based on a well-understood background model dominated by radiogenic sources. The detector concept presented here represents a first step on a compelling path towards sensitivity to the pa...
