Congratulations to the many scientists recognized with the 2026 Breakthrough Prize in Fundamental Physics for their pioneering work on the muon g−2 experiment—one of the most precise tests ever conducted of the Standard Model of particle physics.

The prize honors decades of innovation and collaboration across CERN, Brookhaven National Laboratory, and Fermilab to measure the muon's anomalous magnetic moment with extraordinary precision. 

We are especially proud that one of the award recipients is Young-Kee Kim, a Center for Bright Beams faculty member from the University of Chicago and leader in the Beam Dynamics and Control research theme. 

The success of the muon g−2 program highlights the power of long-term investment in accelerator science and collaboration.

Please join us in congratulating Young-Kee Kim and all of the scientists whose dedication and vision made this remarkable achievement possible.
