The CryoCube...

The experimental characteristic for a CEvNS detection is a low-energy nuclear recoil. For many detector technologies, the total energy of the recoil is not fully transferred into the signature — e.g. scintillation, ionization. In this case, the “quenching factor” needs to be calibrated. I will briefly present a set of the most common techniques to measure these effects with precision, and...
Cryogenic detectors have reached extremely low energy thresholds, making them useful tools to detect sub-keV nuclear recoils induced by Coherent Elastic Neutrino-Nucleus Scattering (CEνNS), or interactions with light Dark Matter. However, these detectors lack calibration for nuclear recoils at this energy scale. We propose using nuclear recoils produced by γ de-excitation after thermal neutron...
The observation of coherent elastic neutrino-nucleus scattering (CEνNS) performed at the COHERENT experiment with a cesium iodide detector and with a liquid argon detector, represents an innovative and powerful tool to study many physical phenomena.
In particular, CEνNS represents a sensitive probe for interactions that are not included in the Standard Model, as for instance interactions...
Neutrino-nucleus interactions play a role in (anti)neutrino scatterings off nuclei, nuclear beta and double beta decays, nuclear electron and muon captures, etc. These processes involve nucleons, protons and neutrons, and their (collective) conglomerates, the nuclei. Neutrino-nucleus interactions are driven by the weak neutral and charged currents, consisting of a vector and an axial-vector...
Neutrino non-standard interactions (NSI) have been extensively explored in the context of dedicated neutrino experiments. However, the next generation of direct detection experiments is on course to observe a significant number of solar neutrino events, and the sensitivities of these experiments within the NSI landscape are yet to be determined. Due to their sensitivity to neutrino-nucleus and...
The $\nu$BDX-DRIFT detector is a directional low-pressure TPC that uses carbon disulfide as target material, but is flexible enough to operate with other target materials such as carbon tetrafluoride or tetraethyllead. Using decay-in-flight neutrino fluxes at Fermilab (NuMI or LBNF), the $\nu$BDX-DRIFT detector offers a CEvNS program complementary to other CEvNS projects at the SNS, the ESS or...
Directional and particle identification capabilities can play a critical role in rare event searches, and it becomes especially challenging when very low energy thresholds need to be reached.

In this talk, we review the current bounds on NSI parameters when combining the recent results from the COHERENT collaboration using CsI and LAr detectors [1]. In addition, we present the expected sensitivities that can be...
Minerals are solid state nuclear track detectors - nuclear recoils in a mineral leave latent damage to the crystal structure. Depending on the mineral and its temperature, the damage features are retained in the material from minutes to timescales much larger than the age of the Solar System. The damage features from the fission fragments left by spontaneous fission of heavy unstable isotopes...
