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...

The Water Cherenkov Test Experiment (WCTE) is a 40-ton water Cherenkov detector operated in the T9 beamline of the East Area at CERN from October 2024 to June 2025. It is instrumented with 97 multi-PMT modules, each consisting of 19 3" PMTs. Charged particles in the beam are characterized by a series of trigger scintillators and aerogel Cherenkov threshold detectors on an event-by-event basis...

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...
