"Muon beam searches to probe the g-2 anomaly"

The recent results from the Fermilab g-2 experiment have reinforced the tension between the experimental measurement and the Standard Model prediction for the anomalous magnetic moment of the muon, now at more than 4-sigma. In this talk I will assume that the anomaly is real and describe how a program of muon beam experiments at a variety of energy scales could definitively uncover the new physics which could resolve it, regardless of the underlying model. At a minimum, there must be one new particle that couples to the muon, which can be discovered at fixed-target muon beam experiments or at a low-energy muon collider. If the new particle has electroweak charges, the observed value of the anomaly permits new particle masses up to the 100 TeV scale, which can be discovered at a muon collider either through direct production or indirectly through their contributions to rare processes. The non-observation of any new physics at a 30 TeV muon collider would have profound implications for naturalness, flavor, and unitarity.
