Currently Playing: Muon g-2 wins Breakthrough Prize in Fundamental Physics

The Muon g-2 experiment at Fermilab received the 2026 Breakthrough Prize in Fundamental Physics for its precision measurement of the muon. The award recognized three generations of the Muon g-2 experiment, which provided the world’s most precise measurement to date of the muon. The experiment began at CERN in the 1970s, shifted to Brookhaven National Laboratory in the 1990s and concluded at Fermilab with final publication in 2025. These Muon g-2 experiments were designed to measure the magnetic moment of the muon with ever-increasing precision, exploring the quantum realm where particles briefly appear and vanish—and where even tiny deviations could point to entirely new laws of nature outside of the current Standard Model of Particle Physics. The latest and most precise measurement of the muon’s magnetic moment was announced by Fermilab in 2025.
