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?
