论文摘要
无效的导致LHC上的新物理搜索如果是富含中间质量的新粒子，则不会排除中间质量的新粒子。如果$α=π/2 $，则两higgs-doublet模型中的I型I可容纳Fermiophopic Light Higgs boson $ h _ {\ rm f} $。较重的$ cp $ - 甚至是希格斯玻色子，以125 GEV的质量解释了观察到的希格斯玻色子。我们首先获得满足理论要求的静态参数空间，$ b $物理学中的中性电流，超过1 TEV的截止量表，Higgs Precision Precision Data和高能量碰撞者的直接撞机搜索边界。我们还通过分析重新归一化组方程来研究高能量表行为。一个重要的结果是，如果$ m_ {h _ {\ rm f}} $是观察到的希格斯玻色子质量的一半，则效率-I类型I可以保持标量电位的稳定性一直延伸至Planck尺度。由于参数空间受到严重限制，特别是对于高截止量表，因此可以很好地预测LHC新希格斯玻色子的多光子状态的信号速率。我们认为$4γ+vv'$（$ v^{（\ prime）} = z，w^\ pm $）的过程是该模型的金色发现通道，因为它们享有几乎没有背景的环境和四个光子的实质性选择效率。
The null results in the new physics searches at the LHC do not exclude an intermediate-mass new particle if it is fermiophobic. Type-I in the two-Higgs-doublet model accommodates a fermiophobic light Higgs boson $h_{\rm f}$ if $α=π/2$. The heavier $CP$-even Higgs boson explains the observed Higgs boson at a mass of 125 GeV. We first obtain the still-valid parameter space satisfying the theoretical requirements, flavor-changing neutral currents in $B$ physics, the cutoff scale above 1 TeV, Higgs precision data, and the direct collider search bounds at high energy colliders. We also study the high energy scale behavior via the analysis of the renormalization group equations. An important result is that the fermiophobic type-I can maintain the stability of the scalar potential all the way up to the Planck scale if $m_{h_{\rm f}}$ is larger than half the observed Higgs boson mass. Since the parameter space is severely curtailed, especially for the high cutoff scale, the signal rates in the multi-photon states of new Higgs bosons at the LHC are well predicted. We suggest the processes of $4γ+VV'$ ($V^{(\prime)}=Z, W^\pm$) as the golden discovery channels for the model since they enjoy an almost background-free environment and substantial selection efficiencies for four photons.
