The Flavor Physics Conference is held every three years, bringing together particle physicists from around the world to discuss the latest developments, challenges, and future directions in understanding the Standard Model and physics beyond it.
In 2025, Dr. Hoh Siew Yan from our group attended the conference, which took place at ICISE, Quy Nhon. He presented a talk on the Muon g-2 Experiment, providing an overview of the long-awaited final results announced earlier in May 2025.
The measurement of the muon’s anomalous precession frequency has now achieved a world-leading precision of 125 parts per billion (ppb), marking more than a two-fold improvement with the inclusion of data from Runs 4, 5, and 6. When compared with the latest Standard Model prediction, now derived primarily from lattice QCD calculations, the discrepancy between theory and experiment has narrowed. However, the lattice-based prediction remains in tension with earlier data-driven approaches, leaving the community eagerly anticipating further theoretical refinement in the coming years.
Although the Muon g-2 experiment has concluded, its results stand as the most stringent test of the Standard Model to date, setting a powerful benchmark for future explorations of new physics.
