abstract
In this article, we demonstrate that the unexpected peak at around $95 \, {\rm GeV}$ 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 $pp \to t \bar t$ with $\overset{(-)}{t} \to H^{\pm} \overset{(-)}{b} \to W^{\pm \, \ast} H \overset{(-)}{b}$ or $pp \to A$ with $A \to W^{\mp} H^{\pm} \to W^{\mp} W^{\pm} H$ or via $pp \to W^{\pm \, \ast} \to H^\pm H$. In this context, we also discuss other Higgs anomalies such as the LEP excess in Higgsstrahlung and the observation of enhanced rates in $t \bar t h$ 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 $80 \, {\rm GeV}$ and $350\, {\rm GeV}$. 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.

Interpreting Light Scalar Excesses and Heavy Scalar Cascades in the $\mu$-Term Extended NMSSM
Viable μNMSSM regions can fit the 95 GeV diphoton/bb anomalies and produce H→hhs and A2→hA1→4b cascades near the 650 and (600,400) GeV CMS structures.

Correlating $A \to \gamma\gamma$ with electric dipole moments in the two Higgs doublet model in light of the diphoton excesses at 95 GeV and 152 GeV
The CP-odd scalar A in the flavor-aligned CP-violating 2HDM can explain the diphoton excesses at 95 and 152 GeV only in tuned regions that survive the electron EDM bound and predict measurable neutron and proton EDMs.

Interplay of $95$ GeV Diphoton Excess and Dark Matter in Supersymmetric Triplet Model
A parameter scan shows the triplet-extended MSSM has regions that fit the 95 GeV diphoton signal, the 125 GeV Higgs mass, and the dark matter relic density simultaneously.

Interpretation of 95 GeV Excess within the Georgi-Machacek Model in Light of Positive Definiteness Constraints
The Georgi-Machacek model keeps viable parameter space for the 95 GeV diphoton and bbbar excesses under positive definiteness constraints, which the paper finds expand the allowed region relative to tree-level bounded...

96 GeV Scalar Boson in the 2HDM with U(1)_H Gauge Symmetry
Type-II and Type-Y two-Higgs-doublet models with a gauged U(1)_H symmetry can accommodate the 96 GeV diphoton, ditau, and bbbar excesses within 2 sigma, with the light scalar mostly a new singlet.

The 96 GeV Diphoton Excess in the Seesaw Extensions of the Natural NMSSM
In the seesaw-extended NMSSM, a ~96 GeV scalar can reproduce both the LEP bbbar and CMS diphoton excesses while the sneutrino dark matter passes all current constraints, in three parameter regions.
