Reanalysis of CMS ttγ data shows a 2.7σ localized excess in m_ℓℓγ at 152 GeV compatible with S → W⁺W⁻γ from a narrow scalar, yielding a ratio σ(S → W⁺W⁻γ)/σ(S → W⁺W⁻) = (2.14 ± 0.77)%.

The 152 GeV real triplet Higgs model predicts more triboson events (WWW, WWZ, VVZ) than LHC data show, making it consistent with but not preferred over the Standard Model.
A minimally extended Georgi-Machacek model accommodates the LHC excesses at 95 GeV and 152 GeV while preserving the 125 GeV Higgs signal and the electroweak rho parameter near unity.
