COSINUS (Cryogenic Observatory for SIgnatures seen in Next-generation Underground Searches) is a direct detection dark matter experiment, whose goal is to perform a model-independent cross-check of the longstanding DAMA/LIBRA claim. The experiment uses NaI crystals as scintillating calorimeters which allow for the detection of both light and phonon signals, giving event-by-event particle...
COSINE-100 is a dark matter search experiment with an array of NaI(Tl) crystals, aiming to confirm the annual modulation that DAMA/LIBRA claims to have detected. It is crucial to reduce the energy threshold, which will not only validate the DAMA/LIBRA experiment but also increase the sensitivity of COSINE-100 for detecting low-mass dark matter. Therefore, it is essential to have a precise and...
The Cryogenic Rare Event Search with Superconducting Thermometers (CRESST) experiment employs scintillating crystals at extremely low temperatures ($\mathcal{O}$(10 mK)) to search for nuclear recoils from hypothetical dark matter (DM) particles. CRESST has achieved thresholds below 100 eV with a wide range of target materials including CaWO$_4$, LiAlO$_2$, Al$_2$O$_3$, and Si. However, the...
AMoRE is an experiment searching for neutrinoless double beta (0nbb) decay using Mo-100 isotopes in molybdate crystal scintillators operated at mK temperatures. It aims to improve an upper limit on the half-life of 0nbb decay, and its sensitivity increases linearly with the experiment exposure if the zero background level in the region of interest (ROI) is achieved. Therefore, it is crucial to...

plant (Germany). The experiment employed four 1 kg...
The DarkSide-50 (DS-50) experiment aims at the direct detection of the Weakly-Interacting Massive Particles (WIMP). Studies have been conducted in both high-mass (>10 GeV/c2) and low-mass (<10 GeV/c2) ranges for WIMPs in DS-50. It is a dual-phase liquid argon time projection chamber (LAr TPC) where Dark Matter (DM), which constitutes five-sixth of all matter in the universe, is expected to...
Liquid noble gas detectors, such as LZ, continue to demonstrate world leading sensitivity to WIMP dark matter for masses above a few GeV. Here an overview of the LZ simulation framework is provided including custom physics lists employed for low energy tracks and deposits, modifications to better model Xe and Gd processes, and external parametric models of scintillation and ionisation...
The antiproton-nucleus ($\bar{p}A$) annihilation is one of the main processes in antimatter studies, as antiparticles are mostly detected through their annihilation. Despite its significance, the process itself is not well established and the lack of models for low energies complicates the simulation of detectors for the experiments conducted at CERN's Antiproton Decelerator.
Previous...
This work represents a comparison of experimental cosmic radiation data obtained at the laboratory of the INFN Genova section and GEMC simulations. GEMC is an interface to the GEANT4 library developed and used at Jefferson Lab. The cosmic radiation was measured by an inorganic scintillating detector (Caesium Iodide Thallium-doped crystal) 6x6x32 cm in size. The detector is surrounded by an...

G4CMP simulates phonon and charge transport in cryogenic semiconductor crystals using the Geant4 toolkit. The transport code is capable of simulating the propagation of acoustic phonons as well as electron and hole charge carriers. Processes for anisotropic phonon propagation, oblique charge-carrier propagation, and phonon emission by accelerated charge carriers are included. The simulation...
The BeEST experiment searches for physics beyond the standard model (BSM) in the neutrino sector by utilizing the electron capture (EC) decay of 7Be. The 7Be is embedded in superconducting tunnel junction (STJ) sensors such that the low-energy (eV-scale) radiation is detected with high energy resolution and efficiency. Modelling of low-energy backgrounds is crucial to understanding potential...
CaWO$_4$ and Al$_2$O$_3$ are well-known target materials for experiments searching for rare events like CE$\nu$NS with NUCLEUS or hypothetical dark matter-nucleus scattering with CRESST. Pushing the detection threshold down to sub-keV energies, experiments are in need for verified and reliable simulations of radioactive background components at sub-keV energies, e.g. based on the widely used...
The low energy threshold necessary for the search of nucleus scattering from sub-GeV/c$^2$ light dark matter (LDM) can be achieved nowadays by solid state detectors, with the disadvantage of limited scalability. The DELight experiment plans to overcome this limit by deploying a target of superfluid helium-4 instrumented with magnetic microcalorimeters, recovering the scalability of noble...

Experiments which aim to measure extremely rare events such as the direct detection of dark matter or coherent elastic neutrino-nucleus scattering are in need of low-background environments to be able to observe a potential signal and distinguish it from the present background. Furthermore, it is crucial to understand the background composition of the measured energy spectra to explore new...
