Chloé Malbrunot (TRIUMF)2024-02-18, 8:30 a.m.Physics Beyond the Standard ModelInvited Oral
Pions are fantastic tools to look for new physics! The PIENU experiment at TRIUMF has provided, to date, the most precise experimental determination of $R^{\pi}_{e/\mu}$, the ratio of pions decaying to positrons relative to muons. While more than an order of magnitude less precise that the Standard Model (SM) calculation, the PIENU result is a precise test of the universality of charged...

In the pursuit of unraveling one of the fundamental questions in physics—why the Universe is matter-dominated—one possible approach is to scrutinize the nature of neutrinos through the investigation of neutrinoless double beta ($0\nu\beta\beta$) decay. The detection of $0\nu\beta\beta$ decay would signify lepton number violation in weak processes and confirm the Majorana nature of neutrinos....

The nEXO experiment is being designed to search for neutrino-less double beta decay ($0\nu\beta\beta$) in a 5000 kg liquid xenon time projection chamber (TPC) enriched to the isotope xenon-136. nEXO requires unprecedentedly low radioactive background levels to achieve its desired sensitivity exceeding $10^{28}$ years. External backgrounds are shielded in part by immersing the TPC and its...

Barium-tagging is a technique being developed as a potential upgrade for an experiment called nEXO. The technique aims to identify single ions of the isotope Ba-136 to confirm the decay of its parent nucleus Xe-136. Due to the event localisation capability of the nEXO detector, with Ba-tagging, the detector volume can be probed for Ba-136. Identification of Ba-136 would serve as unambiguous...

Low background noble liquid-based experiments are among the leading world efforts in neutrino science and dark matter search. They rely on the development of large-scale photon counting technologies to detect noble liquid scintillation in the VUV range (argon at 128 nm or xenon at 175 nm) as a mean to quantify, position, and discriminate meaningful events.
The Université de Sherbrooke is...
