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 …

A bstract The European Spallation Source (ESS), presently well on its way to completion,
will soon provide the most intense neutron beams for multi-disciplinary science. Fortuitously …

In the global landscape of neutrinoless double beta (0 ν β β) decay search, the use of
semiconductor germanium detectors provides many advantages. The excellent energy …

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 …

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 …

Single-molecule fluorescence imaging (SMFI) of gas-phase ions has been proposed for
“barium tagging,” a burgeoning area of research in particle physics to detect individual …

The nature of the neutrino is one of the major open questions in experimental nuclear and
particle physics. The most sensitive known method to establish the Majorana nature of the …

Photomultiplier tubes (PMTs) are often used in low-background particle physics
experiments, which rely on an excellent response to single-photon signals and stable long …

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 …

The Laboratorio Subterráneo de Canfranc (LSC) is the Spanish national hub for low
radioactivity techniques and the associated scientific and technological applications. The …
