摘要
CMS合作最近报告的结果表明,在$m_\phi\approx 95$ GeV时,$\gamma\gamma$和$\tau\tau$通道出现了 "凸起",这为新物理学提供了有趣的暗示。我们发现,一般2HDM(2HDM Type-III)中最轻的希格斯态可以同时完美地容纳这两个过量,以及在$b\bar{b}$通道观测到的LEP长期异常,同时满足所有的理论和实验要求。此外,研究还预言了$pp\to t\bar t H_{\rm SM}$中类似SM的希格斯粒子的增强产生过程,为未来的实验提供了一个可检验的假设。
The recent results reported by the CMS collaboration, indicating"bumps"in the $\gamma\gamma$ and $\tau\tau$ channels at $m_\phi\approx 95$ 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 $pp\to t\bar t H_{\rm SM}$, offering a testable hypothesis for future experiments.
