Description
The Muon g-2 Collaboration recently released a final measurement of the magnetic anomaly of the positive muon (a_μ), based on data taken from 2020 to 2023 at Fermilab. This new dataset contains over 2.5 times the total statistics of the previous publications. The measurement agrees well with the results from 2023 and 2021, with significantly reduced uncertainty largely owing to the increase in statistical precision. The combined Fermilab result is aμ=1165920705(148)×10^{−12} – a precision of 127 ppb. This talk will cover the highlights of the latest measurement and discuss its comparison with the latest Standard Model prediction.
