Sixth Plenary Workshop of the Muon g-2 Theory Initiative

4 Sept 2023, 08:00 → 8 Sept 2023, 17:00 Europe/Zurich

Lecture Hall 099 (ExWi Building)

The Sixth Plenary Workshop of the Muon g-2 Theory Initiative will be held at the University of Bern from 4th to 8th of September 2023 (http://muong-2.itp.unibe.ch/). We plan to hold the workshop as a full in-person meeting.

The anomalous magnetic moment of the Muon (Muon g-2) has received massive attention recently, after the results of Run 1 from the Fermilab E989 experiment were announced. With results from Run 2+3 forthcoming, scrutiny of the prediction in the Standard Model has intensified, including multiple ongoing experimental efforts and theoretical calculations. The aim of the workshop is to discuss recent progress on these developments, geared towards preparing an update of the Standard Model prediction for the Muon g-2.

Important deadlines:

Registration deadline (housing support): June 15, 2023  
Registration deadline (general):  June 30, 2023   
Abstract submission deadline for contributed talks:  June 30, 2023
