In 2021, the Muon g-2 Experiment at Fermilab brought a significant discrepancy between theoretical predictions and experimental measurements of the muon’s anomalous magnetic moment, hinting at new physics. An alternative prediction suggested the Fermilab result aligns with the Standard Model. Alex Keshavarzi delves into the intense showdown in particle physics set for 2025. Despite discrepancies, a new prediction challenges the existence of new physics in the muon g-2. The experiment involves muons traveling in a magnetic field, precessing akin to spinning tops to extract the anomalous magnetic moment. This new insight into particle physics teases intriguing possibilities, challenging the foundations and enticing a glimpse beyond the Standard Model.
