Description

The Mani L. Bhaumik Institute and the Julian Schwinger Foundation are hosting a workshop on the latest developments on the anomalous magnetic moment of the muon. Julian Schwinger, who spent 20 years at UCLA, was the first to calculate the anomalous magnetic moment of the electron in quantum electrodynamics.

To properly assess the significance of the experimental results, tensions in the theoretical evaluation of the hadronic contributions need to first be resolved. To fully interpret the current and upcoming experimental results, it is essential to improve the theoretical uncertainty in difficult to compute hadronic contributions to the anomalous magnetic moment.

The primary purpose of this workshop is to bring together leading experts to assess the situation, resolve tensions between different theoretical calculations in lattice gauge theory and dispersive approaches, and to identify paths towards new breakthroughs. The latest developments on possible beyond the Standard Model explanations will also be discussed.
