2HD plus light pseudoscalar model for a combined explanation of the possible excesses in the CDF MW measurement and (g-2)? with dark matter

The new measurement of the W boson mass performed by the CDF experiment at the Tevatron shows a significant deviation not only with the expectation in the Standard Model but also with other precision measurements performed at LEP, the Tevatron, and the LHC. We nevertheless take this new measurement at face value and interpret it as an effect of new physics. We particularly try to link it with other possible anomalies such as the recent muon g - 2 and consider a scenario that addresses some shortcomings of the Standard Model. We show that a version of a model with two doublets and a light pseudoscalar Higgs fields, supplemented by a stable isosinglet fermion, can simultaneously explain the possible MW and (g - 2)mu anomalies and accounts for the weakly interacting massive particle that could be responsible of the dark matter in the universe.

Automated summary

The new measurement of the W boson mass at Tevatron shows a significant deviation from the Standard Model and other precision measurements. This deviation is interpreted as an effect of new physics and is linked to anomalies such as the muon g-2. A model with two doublets and a light pseudoscalar Higgs field, along with a stable isosinglet fermion, can explain these anomalies and the weakly interacting massive particle responsible for dark matter.
