We suggest an explanation for and explore the consequences of the excessaround 95 GeV in the di-photon and di-tau invariant mass distributions recentlyreported by the CMS collaboration at the Large Hadron Collider (LHC), togetherwith the discrepancy that has long been observed at the Large Electron-Positron(LEP) collider in the $b\bar b$ invariant mass. Interestingly, the most recentfindings announced by the ATLAS collaboration do not contradict, or evensupport, these intriguing observations. Their search in the di-photon finalstate similarly reveals an excess of events within the same mass range, albeitwith a bit lower significance, thereby corroborating and somewhat reinforcingthe observations made by CMS. We have found that all three signatures can beexplained within the general 2-Higgs Doublet Model (2HDM) Type-III. Wedemonstrate that the lightest CP-even Higgs boson in this scenario can explainthe excess in all three channels simultaneously, i.e., in the di-photon, di-tauand $b\bar b$ mass spectra, while satisfying up-to-date theoretical andexperimental constraints. Moreover, the 2HDM Type-III predicts an excess in the$pp\to t\bar t H_{\rm SM}$ production channel of the 125 GeV Higgs bosondiscovered in 2012, with properties (couplings, spin and CP quantum numbers)consistent with those predicted in the Standard Model (SM). This effect iscaused by a up to 18\% enhancement of the Yukawa coupling to top (anti)quarksin comparison to the SM value. Such an effect can be tested soon at the HighLuminosity LHC (HL-LHC), which can either discover or exclude the scenario wesuggest. This unique characteristic of the 2HDM Type-III makes this scenariowith the 95 GeV resonance very attractive for further theoretical andexperimental investigations at the (HL-)LHC and future colliders.
