Radiative muon mass models and (g - 2)μ

Recent measurements of the Higgs-muon coupling are directly probing muon mass generation for the first time. We classify minimal models with a one-loop radiative mass mechanism and show that benchmark models are consistent with current experimental results. We find that these models are best probed by measurements of (g - 2)(mu), even when taking into account the precision of Higgs measurements expected at future colliders. The current (g - 2)(mu) anomaly, if confirmed, could therefore be a first hint that the muon mass has a radiative origin.

Automated summary

Recent measurements have directly probed muon mass generation for the first time, suggesting that benchmark models can be best tested through (g-2)(mu) measurements, potentially indicating a radiative origin of muon mass if the current anomaly is confirmed.
