Probing 95 GeV Higgs in the 2HDM Type-III

Abstract

The recent results reported by the CMS collaboration, indicating "bumps" in the $\gamma \gamma$ and $\tau \tau$ channels at $m_{\varphi }\approx 95$ GeV, provide interesting hints for new physics. We find that the lightest Higgs state of the general 2HDM (2HDM Type-III) can perfectly and simultaneously accommodate the two excesses alongside with the LEP long-standing anomaly observed in the $b\bar{b}$ channel while meeting all theoretical and experimental requirements. Furthermore, the study predicts an enhanced production process for the SM-like Higgs in $pp\to t\bar{t}{H}_{\mathrm{SM}}$, offering a testable hypothesis for future experiments.
