| contents | 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 focus on a leptophilic two-Higgs-doublet model, and propose a 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 $Y_{eμ}\sim 0.6-0.8$ 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. |
