Updated and novel limits on double beta decay and dark matter-induced processes in platinum [PDF]

European Physical Journal C: Particles and Fields, 2023
A 510 day long-term measurement of a 45.3 g platinum foil acting as the sample and high voltage contact in an ultra-low-background high purity germanium detector was performed at Laboratori Nazionali del Gran Sasso (Italy).

Annual modulations from secular variations: relaxing DAMA?

Journal of High Energy Physics, 2020
The DAMA collaboration reported an annually modulated rate with a phase compatible with a Dark Matter induced signal. We point out that a slowly varying rate can bias or even simulate an annual modulation if data are analyzed in terms of residuals ...

Measurement of high energy dark matter from the Sun at IceCube

Journal of High Energy Physics, 2021
It is assumed that heavy dark matter particles (HDMs) with a mass of O(TeV) are captured by the Sun. HDMs can decay to relativistic light dark matter particles (LDMs), which could be measured by km3 neutrino telescopes (like the IceCube detector).

Scalable haloscopes for axion dark matter detection in the 30 μeV range with RADES

Journal of High Energy Physics, 2020
RADES (Relic Axion Detector Exploratory Setup) is a project with the goal of directly searching for axion dark matter above the 30μeV scale employing custom-made microwave filters in magnetic dipole fields.

Reconstruction of the event vertex in the PandaX-III experiment with convolution neural network

Journal of High Energy Physics, 2023
The PandaX-III experiment uses a high-pressure xenon gaseous time projection chamber (TPC) to search for the neutrinoless double beta decay (0νββ) of 136Xe. The absence of the vertex position in the electron drift direction at which the event takes place

Axion-like relics: new constraints from old comagnetometer data

Journal of High Energy Physics, 2020
The noble-alkali comagnetometer, developed in recent years, has been shown to be a very accurate measuring device of anomalous magnetic-like fields. An ultra-light relic axion-like particle can source an anomalous field that permeates space, allowing for

The wavefunction reconstruction effects in calculation of DM-induced electronic transition in semiconductor targets

Journal of High Energy Physics, 2019
The physics of the electronic excitation in semiconductors induced by sub-GeV dark matter (DM) have been extensively discussed in literature, under the framework of the standard plane wave (PW) and pseudopotential calculation scheme.
