Title: Sensitivity of a tonne-scale NEXT detector for neutrinoless double beta decay searches

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 parameter space defined by the inverted hierarchy, and beyond.
