### Event details

The anomalous magnetic moment (g-2) is one of the most precisely measured quantities in fundamental physics. Currently there is a tension between its experimental value and standard-model predictions of three to four standard deviations. This may be a hint of new physics and demands for further investigation. The dominant uncertainties on the theory side are the hadronic vacuum polarization (HVP) and hadronic light-by-light (HLbL) contributions. This talk will explain the lattice QCD position-space approach to HLbL scattering in the muon g-2 developed in Mainz.

### About Particle Physics Theory seminars

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
