The discovery of neutrinoless β β decay could soon be within reach. This hypothetical
ultrarare nuclear decay offers a privileged portal to physics beyond the standard model of …

In the past decade, dual-phase xenon time projection chambers (Xe-TPCs) have emerged
as some of the most powerful detectors in the fields of astroparticle physics and rare-event …

A bstract The Neutrino Experiment with a Xenon TPC (NEXT) searches for the neutrinoless
double-beta (0νββ) decay of 136 Xe using high-pressure xenon gas TPCs with …

We present evidence of non-excimer-based secondary scintillation in gaseous xenon,
obtained using both the NEXT-White time projection chamber (TPC) and a dedicated setup …

A bstract The NEXT experiment aims at the sensitive search of the neutrinoless double beta
decay in 136 Xe, using high-pressure gas electroluminescent time projection chambers. The …

We report a measurement of the half-life of the Xe 136 two-neutrino double-β decay
performed with a novel direct-background-subtraction technique. The analysis relies on the …

A bstract Convolutional neural networks (CNNs) are widely used state-of-the-art computer
vision tools that are becoming increasingly popular in high-energy physics. In this paper, we …

A bstract 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 …

A bstract In experiments searching for neutrinoless double-beta decay, the possibility of
identifying the two emitted electrons is a powerful tool in rejecting background events and …

A bstract Natural radioactivity represents one of the main backgrounds in the search for
neutrinoless double beta decay. Within the NEXT physics program, the radioactivity-induced …
