Abstract
In this article, we demonstrate that the unexpected peak at around 95 GeV as seen recently by CMS in the di-photon final state can be explained within the type-I two-Higgs-doublet model by means of a moderately-to-strongly fermiophobic CP-even Higgs H. Depending on the Higgs mass spectrum, the production of such a H arises dominantly from vector boson fusion or through a cascade in either \( pp\to t\overline{t} \) with \( \overset{\left(-\right)}{t}\to {H}^{\pm}\overset{\left(-\right)}{b}\to {W}^{\pm *}H\overset{\left(-\right)}{b} \) or pp → A with A → W∓H± → W∓W±H or via pp → W± ∗ → H±H. In this context, we also discuss other Higgs anomalies such as the LEP excess in Higgsstrahlung and the observation of enhanced rates in \( t\overline{t}h \) at both the Tevatron and the LHC, showing that parameters capable of explaining the CMS di-photon signal can address the latter deviations as well. The Higgs spectra that we explore comprise masses between 80 GeV and 350 GeV. While at present all constraints from direct and indirect searches for spin-0 resonances can be shown to be satisfied for such light Higgses, future LHC data will be able to probe the parameter space that leads to a simultaneous explanation of the discussed anomalies.
