Demonstration of the event identification capabilities of the NEXT-White detector

Journal of High Energy Physics, 2019
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 therefore improving the overall sensitivity of the experiment.

Improved axion haloscope search analysis

Journal of High Energy Physics, 2021
One of the most significant and practical figures of merit in axion haloscope searches is the scanning rate, because of the unknown axion mass. Under the best experimental parameters, the only way to improve the figure of merit is to increase the ...

Energy calibration of the NEXT-White detector with 1% resolution near Q ββ of 136Xe

Journal of High Energy Physics, 2019
Excellent energy resolution is one of the primary advantages of electroluminescent high-pressure xenon TPCs. These detectors are promising tools in searching for rare physics events, such as neutrinoless double-beta decay (ββ0ν), which require precise ...

Migdal effect and photon Bremsstrahlung: improving the sensitivity to light dark matter of liquid argon experiments

Journal of High Energy Physics, 2020
The search for dark matter weakly interacting massive particles with noble liquids has probed masses down and below a GeV/c 2. The ultimate limit is represented by the experimental threshold on the energy transfer to the nuclear recoil.

Axion dark matter detection by superconducting resonant frequency conversion

Journal of High Energy Physics, 2020
We propose an approach to search for axion dark matter with a specially designed superconducting radio frequency cavity, targeting axions with masses m a ≲ 10 −6 eV. Our approach exploits axion-induced transitions between nearly degenerate resonant modes
