The discovery of neutrinoless double beta decay is one of the main targets of particle physics nowadays. It would demonstrate that neutrinos are Majorana particles, which does not fit in the Standard Model as it currently stands. NEXT is an experiment aiming for such discovery. The detector, a high-pressure xenon TPC, provides two remarkable features for searching this decay: an excellent energy resolution (below 1% FWHM at Qββ) and topological signature for background rejection. This detection technique makes it possible to reach a sensitivity to T1/2 of 5·1025 y with an exposure of 300 kg · y, competitive with the leading experiments in the field.
