Sensitivity of NEXT-100 to neutrinoless double beta decay uri icon

abstract

  • 2016, The Author(s). Abstract: NEXT-100 is an electroluminescent high-pressure xenon gas time projection chamber that will search for the neutrinoless double beta (0) decay of 136Xe. The detector possesses two features of great value for 0 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 4 104 counts keV1 kg1 yr1. Accordingly, the detector will reach a sensitivity to the 0-decay half-life of 2.8 1025 years (90% CL) for an exposure of 100 kgyear, or 6.0 1025 years after a run of 3 effective years.[Figure not available: see fulltext.]
