Status and physics potential of NEXT-100    [PDF]

The NEXT-100 time projection chamber, currently under construction, will search for neutrinoless double beta decay (bb0nu) using 100-150 kg of high-pressure xenon gas enriched in the Xe-136 isotope to ~91%. The detector possesses two important features for bb0nu searches: very good energy resolution (better than 1% FWHM at the Q value of Xe-136) and event topological information for the distinction between signal and background. Furthermore, the technique can be extrapolated to the ton-scale, thus allowing the full exploration of the inverted hierarchy of neutrino masses.
