Dominik Stöckinger (IKTP): The new muon g-2 result from the Fermilab experiment and its theoretical interpretation

Abstract:
The muon g-2 is one of the most precisely known quantities in particle
physics and it provides an intriguing probe of all aspects of the SM
and potential ideas for physics beyond the SM (BSM).
20 years ago the Brookhaven muon g-2 experiment observed a tantalizing
deviation from the SM prediction. This has motivated a new, improved
measurement at Fermilab and a huge effort by the theory community.
Now, the Fermilab experiment has published its first results,
confirming the deviation and strengthening the indications for BSM
physics. The Dresden group has contributed to the experiment and to
the worldwide Theory Initiative SM prediction and is investigating
potential BSM interpretations of the result.
In the talk we provide an overview of the situation and discuss in
particular: What are the key principles of the experiment, why is muon
g-2 sensitive to all known particles and interactions, and what is the
status of the SM theory prediction? What are possible BSM
interpretations of the result and why is g-2 such a particularly
interesting probe of the muon mass generation mechanism and dark matter?
