Title: Probing new physics with the PIONEER experiment
 
Abstract: PIONEER is a proposed next-generation rare pion decay experiment at PSI. Its main goal in phase 1 is to measure the helicity suppressed pi -> e nu decay with an order of magnitude better precision compared to existing measurements. In phase 2 and 3, the goal is a precision measurement of the extremely rare pion beta decay pi+ -> pi0 e nu. I will give an overview of the experiment, describe its motivation and new physics sensitivities, and also outline a possible dark sector program at PIONEER.
