The Standard Model (SM) of particle physics has been very successful in describing the elementary particles and their interactions. The search for neutrinoless double-beta decay ($0\nu \beta \beta$) offers a way to probe for physics beyond the SM. Observation of $0\nu \beta \beta$ would unambiguously demonstrate violation of lepton number. Additionally, it could also help explain the observed...

Radioactivity in particulates contributes significantly to the background in ultra-low background experiments. The alpha generated from dust provides a degraded energy signal on the detector that mimics low-energy nuclear recoil events, which is background to rare event particle detectors, especially dark matter search experiments. A particulate cleaning station, which includes controlled gas...

LoLX is a small scale R&D experiment, hosted at McGill University, which aims to study the properties of liquid xenon (LXe) scintillation light and characterize Cherenkov light emission in LXe with cutting-edge photo-detection technology. It supports next-generation rare-decay experiments, such as nEXO, which will search for neutrinoless double-beta decay in LXe. Interactions in nEXO produce...

I present studies on a deep convolutional autoencoder originally designed to remove electronic noise from a p-type point contact high-purity germanium (HPGe) detector. With their intrinsic purity and excellent energy resolutions, HPGe detectors are suitable for a variety of rare event searches such as neutrinoless double-beta decay, dark matter candidates, and other exotic physics. However,...

nEXO is a proposed tonne-scale experiment which aims to search for neutrinoless double beta ($0\nu \beta \beta$) decay in the isotope ${}^{136}$Xe. The observation of $0\nu \beta \beta$ decay would demonstrate lepton number violation in weak processes and the Majorana nature of neutrinos. This would be an explicit signature of physics beyond the Standard Model and also may provide insight into the...
