PLEASE NOTE THE UNUSUAL TIME (14H00)

The Muon g-2 Experiment at Fermi National Accelerator Laboratory was designed to measure the muon magnetic anomaly, aµ, with a target precision of 140 parts-per-billion; a four-fold improvement over the former measurement from the early 2000s at Brookhaven National Laboratory (BNL). The experiment was motivated by the ~3.5 standard deviation between the BNL result and the Standard Model prediction of aµ; which could be a hint of new physics.

The Muon g-2 collaboration recently finished the analysis of the final three years of data taking. The average of all six years of data has resulted in a final precision of 127 ppb, surpassing our design goals. This new result will remain a benchmark test for any future extension of the Standard Model for years to come. The talk will give a short history, an overview of the experimental technique, and present the details of the analysis and the final result.

Refreshments will be served at 13:30 .
