Connecting dark matter, baryogenesis and neutrinoless double beta decay in a $A_{4}\otimes Z_{8}$ based $\nu$2HDM [PDF]

open access: yes, 2023
In this paper, we discuss the impact of neutrino phenomenology and related cosmology on an $A_{4}\otimes Z_{8}$ symmetric $\nu$2HDM along with an addition of a new particle, i.e. a gauge singlet(S).

Boosting background suppression in the NEXT experiment through Richardson-Lucy deconvolution

open access: yesJournal of High Energy Physics, 2021
Next-generation neutrinoless double beta decay experiments aim for half-life sensitivities of ∼ 1027 yr, requiring suppressing backgrounds to < 1 count/tonne/yr.

Limits on interactions between weakly interacting massive particles and nucleons obtained with NaI(Tl) crystal detectors

open access: yesJournal of High Energy Physics, 2019
Limits on the cross section for weakly interacting massive particles (WIMPs) elastic scattering on nuclei in NaI(Tl) detectors at the Yangyang Underground Laboratory are obtained from a 2967.4 kg·day data exposure.

Cold dark matter, radiative neutrino mass, μ → e γ, and neutrinoless double beta decay [PDF]

open access: yes, 2006
Two of the most important and pressing questions in cosmology and particle physics are: (1) what is the nature of cold dark matter? and (2) will near-future experiments on neutrinoless double beta decay be able to ascertain that the neutrino is a ...

Exploring the ultra-light to sub-MeV dark matter window with atomic clocks and co-magnetometers

open access: yesJournal of High Energy Physics, 2019
Particle dark matter could have a mass anywhere from that of ultralight candidates, m χ ∼ 10−21 eV, to scales well above the GeV. Conventional laboratory searches are sensitive to a range of masses close to the weak scale, while new techniques are ...

First results of the CAST-RADES haloscope search for axions at 34.67 μeV

open access: yesJournal of High Energy Physics, 2021
We present results of the Relic Axion Dark-Matter Exploratory Setup (RADES), a detector which is part of the CERN Axion Solar Telescope (CAST), searching for axion dark matter in the 34.67 μeV mass range.

The 0ν2β-decay CROSS experiment: preliminary results and prospects

open access: yesJournal of High Energy Physics, 2020
Neutrinoless double-beta decay is a key process in particle physics. Its experimental investigation is the only viable method that can establish the Majorana nature of neutrinos, providing at the same time a sensitive inclusive test of lepton number ...

Searching for dark absorption with direct detection experiments

open access: yesJournal of High Energy Physics, 2017
We consider the absorption by bound electrons of dark matter in the form of dark photons and axion-like particles, as well as of dark photons from the Sun, in current and next-generation direct detection experiments.

Demonstration of neutrinoless double beta decay searches in gaseous xenon with NEXT

open access: yesJournal of High Energy Physics, 2023
The NEXT experiment aims at the sensitive search of the neutrinoless double beta decay in 136Xe, using high-pressure gas electroluminescent time projection chambers. The NEXT-White detector is the first radiopure demonstrator of this technology, operated
