Description
Statistically significant excesses exist at around 152 GeV in associated di-photon production contained in the sidebands of SM Higgs analyses. They are most pronounced in the $\gamma \gamma + \tau$, $\gamma \gamma + \text{MET}$, $\gamma \gamma + \geq 1 \ell +\geq 1b$, $\gamma \gamma + 4 j$ signal regions, and can be explained by the Drell-Yan production of new Higgs bosons, i.e. $p p \to W \to H^\pm 𝐻$. In this context, we first examine the excesses in a simplified model approach, considering the decays of $H^\pm \to \tau \nu, t b, WZ$. We then specialize our analysis for the real Higgs triplet and two-Higgs doublet models, resulting in a combined significance of $\approx 4 \sigma$ and $\approx 4.3 \sigma$, respectively.
