The detector possesses two features of great value for 0¿ßß searches: energy resolution better than 1% FWHM at the Q value of 136Xe 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. Accordingly, the detector will reach a sensitivity to the 0¿ßß-decay half-life of 2.8 × 1025 years (90% CL) for an exposure of 100 kg·year, or 6.0 × 1025 years after a run of 3 effective years.Figure not available: see fulltext.]2016http://zaguan.unizar.es/record/5617610.1007/JHEP05(2016)159http://zaguan.unizar.es/record/56176oai:zaguan.unizar.es:56176info:eu-repo/grantAgreement/EUR/FP7/ERC-339787-NEXTinfo:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio-2010/CSD2008-00037info:eu-repo/grantAgreement/ES/MINECO/FIS2014-53371-C04JOURNAL OF HIGH ENERGY PHYSICS 2016, 5 (2016), [30 pp]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
