The ‘Data-Directed Paradigm’ (DDP) is a search methodology that efficiently explores possibilities for new physics within a vast number of spectra featuring smooth-falling Standard Model backgrounds. DDP deviates from the traditional analytical approach by sidestepping the requirement for a simulated or functional-form-based background estimate. Instead, it uses a neural network trained to...

At the Francium Trapping Facility located at TRIUMF our group uses laser cooling and atom trapping techniques to confine Fr and Rb atoms in a magneto-optical trap allowing us to investigate highly forbidden optical transitions in these atoms with precision laser spectroscopy. For Fr, these investigations are important precursors to future atomic parity-violating (APV) experiments. Atomic...

The TRIUMF Ultra Cold Advanced Neutron (TUCAN) Collaboration is developing an apparatus to measure the neutron electric dipole moment (nEDM) to a sensitivity of 10−27 ecm, an order of magnitude improvement over the current best limit. The measurement will be conducted over around 105 experiment cycles using spin-polarized ultracold neutrons produced by the high-intensity TUCAN source in a...

Antimatter remains one of the most vital, yet mysterious areas of particle physics. The deficiency of antimatter in nature, despite its theoretically predicted abundance, leaves questions regarding our understanding of fundamental symmetries. Antihydrogen is the antimatter counterpart of the hydrogen atom, and it provides a simple antimatter system to test these symmetries, such as...

One possible extension to the Standard Model of Particle Physics (SM) is one which provides a mechanism, active in the early universe that has lead to the matter-antimatter asymmetry that we observe today. One of the most prominent proposed solutions to this asymmetry relates this imbalance of matter and antimatter to new sources of CP violation which may manifest, for instance, in permanent...

The detection of dark matter is currently one of the leading challenges in particle physics. The DEAP-3600 experiment, the largest argon dark matter detector in the world, uses 3.3 tonnes of liquid argon and 255 photomultiplier tubes to detect scintillation light produced by a dark matter particle scattering on an argon nucleus. Since the interaction of dark matter scattering on argon is such...

Silicon photomultipliers (SiPMs) are the photo-detection technology of choice for future noble-liquid scintillator rare-event search experiments, both in neutrino-less double beta decay and dark matter. The Light only Liquid Xenon (LoLX) experiment is a small-scale R&D liquid xenon (LXe) detector located at McGill University. LoLX aims to perform detailed characterization of SiPM performance...
