Experimental updates on development of accelerator-driven ion source at TRIUMF to benchmark Ba-tagging techniques for future neutrinoless double beta decay searches

D. Ray, M. Marquis, A. V. Balbuena +4

Neutrinoless double beta decay () could provide a way to probe physics beyond the Standard Model of particle physics. The proposed nEXO experiment aims to search for $0ν΅

Aluminum-Based Superconducting Tunnel Junction Sensors for Nuclear Recoil Spectroscopy

Spencer L. Fretwell, Connor Bray, Inwook Kim +31

The BeEST experiment is searching for sub-MeV sterile neutrinos by measuring nuclear recoil energies from the decay of Be implanted into superconducting tunnel junction (STJ) s…

Shake-up and shake-off spectra in the electron capture decay of atomic Be

Mauro Guerra, Inwook Kim, Stephan Friedrich +33

The most stringent laboratory-based experimental limits on the existence of sub-MeV sterile neutrinos are currently set by decay spectroscopy of radioactive Be embedded into su…

Direct measurement of Cu(,)Ni precludes a strong NiCu cycle in Type-I X-ray bursts

N. Bhathi, J. S. Randhawa, R. Kanungo +36

Model-observation comparisons of type-I X-ray bursts (XRBs) can reveal the properties of accreting neutron star systems, including the neutron star compactness. XRBs are powered by…

Ultra-sensitive radon assay using an electrostatic chamber in a recirculating system

nEXO Collaboration, A. Anker, P. A. Breur +138

Rare event searches such as neutrinoless double beta decay and Weakly Interacting Massive Particle detection require ultra-low background detectors. Radon contamination is a signif…

Sensitivity of nEXO to Xe Charged-Current Interactions: Background-free Searches for Solar Neutrinos and Fermionic Dark Matter

G. Richardson, B. G. Lenardo, D. Gallacher +135

We study the sensitivity of nEXO to solar neutrino charged-current interactions, XeCs, as well as analogous interactions predicted by m…
