Summary
NEXT-100 is an electroluminescent high-pressure xenon gas time projection chamber that will search for the neutrinoless double beta (0νββ) decay of $^{136}$Xe. The detector possesses two features of great value for 0νββ searches: energy resolution better than 1% FWHM at the Q value of $^{136}$Xe and track reconstruction for the discrimination of signal and background events. This combination results in excellent sensitivity, as discussed in this paper. Material-screening measurements and a detailed Monte Carlo detector simulation predict a background rate for NEXT-100 of at most 4 × 10$^{–4}$ counts keV$^{–1}$ kg$^{–1}$ yr$^{–1}$. Furthermore, the detector will reach a sensitivity to the 0νββ-decay half-life of 2.8 × 10$^{25}$ years (90% CL) for an exposure of 100 kg·year, or 6.0 × 10$^{25}$ years after a run of 3 effective years.
