Story summary

Physicists at Fermilab have made a groundbreaking achievement by measuring the muon's magnetic anomaly with unprecedented precision—127 parts per billion. This remarkable result not only reinforces previous findings but also aligns with the Standard Model, casting doubt on the existence of new physics. The comprehensive data collected from 2021 to 2023 will soon be unveiled in Physical Review Letters.
