Sensitivity of a tonne-scale NEXT detector for neutrinoless double-beta decay s...
Adams, C.; Álvarez, V; Arazi, L.; Arnquist, I. J.; Azevedo, C. D. R; Bailey, K.; Ballester, F.; Benlloch-Rodríguez, J. M.; Borges, F. I. G. M.The Neutrino Experiment with a Xenon TPC (NEXT) searches for the neutrinoless double-beta (0 ) decay of 136Xe using high-pressure xenon gas TPCs with electroluminescent amplification. A scaled-up version of this technology with about 1 tonne of enriched xenon could reach in less than 5 years of operation a sensitivity to the half-life of 0 decay better than 1027 years, improving the current limits by at least o...
Boosting background suppression in the NEXT experiment through Richardson-Lucy ...
Simón, A.; Ifergan, Y.; Redwine, A. B.; Weiss-Babai, R.; Arazi, L.; Adams, C.; Almazán, H.; Álvarez, V.; Aparicio, B.; Aranburu, A. I.; Arnquist, I. J.Submitted to JHEP; Next-generation neutrinoless double beta decay experiments aim for half-life sensitivities of ~$10^{27}$ yr, requiring suppressing backgrounds to <1 count/tonne/yr. For this, any extra background rejection handle, beyond excellent energy resolution and the use of extremely radiopure materials, is of utmost importance. The NEXT experiment exploits differences in the spatial ionization patterns...
