全球希格斯粒子作为LHC复合性的信号

The Global Higgs as a Signal for Compositeness at the LHC

Sylvain Fichet, Gero von Gersdorff, Eduardo Ponton, Rogerio Rosenfeld

摘要:

复合Higgs模型中的整体破缺真空的径向激发,被称为“整体Higgs”,是近年来的研究热点。在本文中,我们研究了在13 TeV LHC检测这种复合标量的前景。我们计算了全球希格斯粒子的产生率,并估计了全球希格斯粒子衰变成顶夸克对和希格斯粒子和电弱规范玻色子以及随后的强子衰变的发现潜力。整体希格斯粒子也可能衰变为费米子共振,如顶级伙伴,为复合性提供了一个新的窗口。我们表明,顶级合作伙伴射流可以有效地解决在某些地区的参数空间。这种“加强的顶级合伙人”的签名值得开发专门的子结构分析。

英文摘要:

The radial excitation of the global symmetry-breaking vacuum in composite Higgs models, called the "global Higgs", has been recently a focus of investigation. In this paper we study the prospects for detecting this composite scalar at the 13 TeV LHC. We compute the global Higgs production rates and estimate the discovery potential of a global Higgs decaying into top quark pairs and into Higgs and electroweak gauge bosons with subsequent hadronic decays. The global Higgs may also decay into fermion resonances such as top partners, providing a new window into compositeness. We show that top partner jets can be effectively unresolved in some regions of the parameter space. Such "boosted top partner" signatures would deserve the development of dedicated substructure analyses.
