Muon g-2 experiment returns with new precision measurement

In 2021, the Muon g-2 experiment at Fermilab created headlines around the world: it found strong evidence for physics beyond the Standard Model of elementary particles and forces. Now scientists working on the experiment have a new result based on more data. They have achieved the world's most precise measurement of the anomalous magnetic moment of the muon. The new value for muon g-2 strengthens the 2021 result and doubles its precision. This sets up a showdown between theory and experiment 20 years in the making: Scientists of the Muon g-2 Theory Initiative aim to have a new, improved prediction available in the next couple of years
