Backgrounds and sensitivity of the NEXT double beta decay experiment 2016 Access copy available to the general public Unrestricted NEXT (Neutrino Experiment with a Xenon TPC) is a neutrinoless double-beta (ßß0¿ßß0¿) decay experiment that will operate at the Canfranc Underground Laboratory (LSC). It is an electroluminescent high-pressure gaseous xenon Time Projection Chamber (TPC) with separate read-out planes for calorimetry and tracking. Energy resolution and background suppression are the two key features of any neutrinoless double beta decay experiment. NEXT has both good energy resolution (<1% FWHM) at the Q value of 136Xe and an extra handle for background identification provided by track reconstruction. With the background model of NEXT, based on the detector simulation and the evaluation of the detector radiopurity, we can determine the sensitivity to a measurement of the ßß2¿ßß2¿ mode in NEW and to a ßß0¿ßß0¿ search in NEXT100. In this way we can predict the background rate of 5×10-4 counts/(keV kg yr)5×10-4 counts/(keV kg yr), and a sensitivity to the Majorana neutrino mass down to 100 meV after a 5-years run of NEXT100. info:eu-repo/grantAgreement/ES/MINECO/FPA2009-13697-C04-04 info:eu-repo/grantAgreement/ES/MINECO/FIS2012-37947-C04 info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio-2010/CSD2008-00037 info:eu-repo/grantAgreement/EC/FP7/339787/EU/Towards the NEXT generation of bb0nu experimets/NEXT info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 0.313 2016 Nuclear and High Energy Physics 2016 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Ferrario, P.
