Do muons wobble faster than expected?

    The Cern Courier explores the experimental results and theoretical calculations used to predict ‘muon g-2’ – one of particle physics’ most precisely known quantities and the subject of a fast-evolving anomaly.

    Is there a fifth force of nature?

      In the quest to understand the fundamental forces that govern our universe, the Standard Model of particle physics has long stood as the cornerstone. Recent experimental discrepancies like those from Fermilab’s Muon g-2 experiment, have stirred the physics community, suggesting that the muon’s behavior under magnetic fields might not fully align with Standard Model prediction.

      The muon fails to upend physics as we know it

        The unusually large Muon has threatened the Standard Model for decades, but new data parks the particle inside the confines of established physics. The BMW Collaboration’s recently posted research suggests the difference between the muon’s predicted anomalous magnetic moment and that predicted by the Standard Model is not as large as previous findings suggested.
