Abstract: (APS)

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

p p \to (μ^{+} μ^{+} j j + E_{T})

and

p p \to (μ^{+} μ^{-} τ^{+} τ^{-} + X)

signals.
