Search for a lighter Higgs in Two Higgs Doublet Models

摘要:

我们考虑目前的两个希格斯双重模型的约束,无论是从大型强子对撞机在运行1和其他来源,以探索约束的可能性,中性标量或赝标量粒子轻于125 GeV的希格斯玻色子。目前的数据还没有完全排除这种较轻的粒子。我们表明,一些新的约束条件,可以得到在大型强子对撞机,如果这样的搜索进行的实验合作,因此,我们鼓励继续进行光双光子共振搜索在$\sqrt{s}=$ 13 TeV的背景下的两个希格斯双态模型。

英文摘要:

We consider present constraints on Two Higgs Doublet Models, both from the LHC at Run 1 and from other sources in order to explore the possibility of constraining a neutral scalar or pseudo-scalar particle lighter than the 125 GeV Higgs boson. Such a lighter particle is not yet completely excluded by present data. We show with a simplified analysis that some new constraints could be obtained at the LHC if such a search is performed by the experimental collaborations, which we therefore encourage to continue carrying out light diphoton resonance searches at $\sqrt{s}=$ 13 TeV in the context of Two Higgs Doublet Models.
