151. Searching for New Physics with Pions

Chloé Malbrunot (TRIUMF)

Physics Beyond the Standard Model

Invited 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 $R_{e/\mu }^{\pi }$, 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...

100. A Calibration System for the nEXO Muon Veto

Samin Majidi (McGill University)

Contributed Oral

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....

121. Simulation of Cosmogenic Backgrounds to nEXO

Regan Ross (McGill University)

Contributed Oral

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...

124. Unraveling Secrets of the Universe, One Barium Ion at a Time: A Barium Tagging Technique for the nEXO Experiment

Hussain Rasiwala (McGill University)

Nuclear Physics

Contributed Oral

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...

132. VUV SPAD Technologies for Neutrino Experiments

Jérôme Deshaies (Université de Sherbrooke)

18/02/2024, 09:45

Contributed Oral

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...
