Anthropic solution to the magnetic muon anomaly: the charged see-saw

We present models of new physics that can explain the muon g - 2 anomaly in accord with the assumption that the only scalar existing at the weak scale is the Higgs, as suggested by anthropic selection. Such models are dubbed charged see-saw because the muon mass term is mediated by heavy leptons. The electroweak contribution to the g - 2 gets modified by order one factors, giving an anomaly of the same order as the observed hint, which is strongly correlated with a modification of the Higgs coupling to the muon.
