Abstract：
After the final result from the Fermi lab E989 experiment, the world average for the
anomalous magnetic moment of the muon boasts a precision of 124 ppb. Theory lags behind
by about a factor of four, necessitating a corresponding improvement to fully leverage
the experimental precision in the search for physics beyond the Standard Model. The
limiting factor in the theoretical precision concerns hadronic contributions, primarily
hadronic vacuum polarization and, to a lesser degree, hadronic light-by-light scattering.
Avenues to achieve the required level of precision involve both improved lattice-QCD
calculations and data-driven determinations, and ideally both at a similar level of
precision. In the talk, I will provide an overview of the current status focusing on
the data-driven approach, with special emphasis on the different ways in which a future
Super Tau-Charm Factory could contribute in this endeavor.
Brief CV for speaker：
Prof. Dr. Martin Hoferichter obtained his PhD degree in 2012 at the University of Bonn.
Then he worked at a postdoc at Bern University (2012-2014), and then at the Technical
University of Darmstadt (2014-2015). He was are search assistant professor at the Institute
for Nuclear Theory, University of Washington from 2015 to 2020, and has worked at Albert
Einstein Center for Fundamental Physics, Institute for Theoretical Physics, University of
Bern since 2020.
