The measurement of the muon anomalous magnetic moment ('g-2') has long served as a precision test of the Standard Model (SM). The Fermilab Muon g-2 experiment has recently completed a precision measurement with a sensitivity of 0.13 ppm, setting a benchmark for years to come. On the theory side, the SM prediction continues to exhibit internal tensions that require further clarification.

 

The field is now entering a post-Fermilab era, in which both the experimental status and future directions call for careful reassessment. In this talk, I will review key lessons learned from the Fermilab programme, focusing in particular on the intrinsic limitations that emerge as the experiment approaches the 0.1-ppm. Building on recent community-wide assessments, I will discuss possible directions for next-generation muon g-2 measurements, and outline how the field can continue to play an important role in precision tests of the SM and new physics in the coming decades. 

 

Bio: Ce Zhang is a postdoctoral researcher in the muon group at the University of Liverpool. His research centres on the muon g-2 experiment. During his PhD, he worked on the J-PARC muon g-2 experiment, where he realised the muon cooling techniques via laser ionization of muonium, and developed a diffusion model for muons in aerogel targets. As a postdoctoral researcher in Liverpool, he has been involved in the Fermilab Muon g-2 experiment and made significant contributions to the final precession data analysis and to beam dynamics studies, while also participating in other muon-related experimental activities.
