Invited Speaker / Conférencier(ère) invité(e)

PIONEER is a rare pion decay experiment that will run at the Paul Scherrer Institute (PSI) in Switzerland. In its initial phase, the primary objective is to significantly improve the measurement of the pion leptonic decay branching ratio:
$R_{e/\mu} = \mathcal{B}(\pi \to e\nu(\gamma)) / \mathcal{B}(\pi \to \mu\nu(\gamma))$. PIONEER aims to surpass the precision of the current best...

Deep beneath the Canadian Shield, within the confines of the SNOLAB underground laboratory situated at the Vale-Creighton mine southwest of Sudbury, Ontario, lies the SNO+ experiment. This experiment, the successor to the SNO experiment, aims to observe neutrino-less double beta decay. SNO+ has been operational as a liquid scintillator neutrino detector since 2022. Specific hardware had been...

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

The Deep Underground Neutrino Experiment (DUNE) is a next-generation particle physics experiment designed to study neutrino oscillation (in which neutrinos of one flavour transform into other flavours as they travel) alongside a broad program of other research. It will consist of two detector facilities, the Near Detector (ND) at the Fermi National Accelerator Laboratory (Fermilab) near...

586. Diffusion of radon daughters in polymer

Oral (Non-Student) / Orale (non-étudiant(e))

Radon and its decay products constitute significant sources of background in rare-event experiments, including dark matter and neutrino searches, due to their unavoidable origin from naturally occurring uranium. Both 222Rn and its long-lived progeny, 210Pb, can diffuse from detector material surfaces, resulting in persistent background contributions in low-background experiments. To study this...
