带电和中性的希格斯玻色子玻色子与六个底夸克的末态

Charged and neutral Higgs bosons in final states with six bottom quarks

Radovan Dermisek, Enrico Lunghi, Navin McGinnis, Seodong Shin

摘要:

在含矢量夸克的两个Higgs二重态模型的推广中,矢量夸克的衰变很容易被通过带电或中性希格斯玻色子玻色子的级联衰变所控制,从而导致6个顶夸克或底夸克的签名。由于顶夸克衰变也包含底夸克,因此处于末态的6个底夸克是一大类可能的衰变链的共同特征。我们提出了一个搜索策略,专注于这个最终状态,并找到矢量夸克和希格斯玻色子,可以探索在大型强子对撞机的质量范围。在其他结果中,与没有矢量物质的模型相比,对带电希格斯玻色子的敏感性超过2 TeV。

英文摘要:

In extensions of two Higgs doublet models with vectorlike quarks, the decays of vectorlike quarks may be easily dominated by cascade decays through charged or neutral Higgs bosons leading to signatures with 6 top or bottom quarks. Since top quark decays also contain bottom quarks, the 6 bottom quarks in final states is a common signature to a large class of possible decay chains. We present a search strategy focusing on this final state and find the mass ranges of vectorlike quarks and Higgs bosons that can be explored at the Large Hadron Collider. Among other results the sensitivity to the charged Higgs boson, extending above 2 TeV, stands out when compared to models without vectorlike matter.
