This study reveals the correlation between the recent high precision measurement of the W-boson mass by the CDF Collaboration and the muon (g-2) anomaly in the context of the two Higgs doublet model. It discusses the explanation mechanism and requirements for this correlation.
We show an interesting correlation between the recent high precision measurement of the W-boson mass by the CDF Collaboration and the muon (g-2) anomaly in the context of the two Higgs doublet model. One-loop diagrams involving the exchange of neutral scalar bosons can explain the muon (g-2), which, however, requires significant mass splittings among members of the second Higgs doublet. These splittings also generate a positive shift in the mass of the W boson, consistent with the recent CDF measurement. The charged and neutral scalars of the model cannot be heavier than about 600 GeV for a simultaneous explanation of the two anomalies. The entire parameter space of the model can be tested at the LHC by a combination of same sign dimuon signals in pp -> (mu(+)mu(+ )jj + (sic)(T) and pp -> (mu+mu- tau(+)tau(-) + X) signals.
