Hints of a new leptophilic Higgs sector

We show that a new leptophilic Higgs sector can resolve some intriguing anomalies in current experimental data across multiple energy ranges. Motivated by the recent CMS excess in the resonant eμ channel at 146 GeV, we consider a leptophilic two-Higgs-doublet model, and propose a novel resonant production mechanism for the neutral components of the second Higgs doublet at the LHC using the lepton content of the proton. Interestingly, the same Yukawa coupling Yeμ∼0.65-0.81 that explains the CMS excess also addresses the muon (g-2) anomaly. Moreover, the new Higgs doublet also resolves the recent CDF W-boson mass anomaly. The relevant model parameter space will be completely probed by future LHC data.
