Radiative muon mass models and (g − 2)μ
Michael J. Baker, Peter Cox, Raymond R. Volkas
Abstract
A bstract 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) μ , even when taking into account the precision of Higgs measurements expected at future colliders. The current ( g − 2) μ anomaly, if confirmed, could therefore be a first hint that the muon mass has a radiative origin.
