December 3rd through 5th, 2018
UCLA Faculty Center
Organizers: Zvi Bern (Mani L. Bhaumik Institute), Tom Blum (University of Connecticut), Lance Dixon (SLAC), William Marciano (Brookhaven National Laboratory)
2018 is Julian Schwinger's Centennial. To help celebrate Julian Schwinger's legacy, the Mani L. Bhaumik Institute and the Julian Schwinger Foundation will be holding a workshop on the latest developments on the anomalous magnetic moment of leptons, especially the muon. A long-standing 3 sigma discrepancy between theory and experiment points towards new physics beyond the Standard Model. Is it real? This workshop is particularly timely given the ongoing Fermilab muon g-2 experiment, which will reach unprecedented precision. In order to fully interpret the upcoming experimental results, it is essential to improve the theoretical uncertainty in difficult to compute hadronic contributions, especially to the light-by-light contribution. Recent progress in lattice gauge theory calculations suggests that it is possible to achieve this. The primary purpose of this workshop is to bring together leading experts to assess the situation and to identify paths towards new breakthroughs.
