论文摘要
在两个具有矢量夸克的Higgs Doublet模型的扩展中，通过带电或中性的Higgs玻色子，级联衰变很容易由矢量夸克的衰减占主导地位。由于顶级夸克腐烂也包含底部夸克，因此最终状态下的6个底部夸克是大量可能的衰减链的常见签名。我们提出了一个搜索策略，重点是这种最终状态，并找到可以在大型强子对撞机上探索的矢量夸克和希格斯玻色子的质量范围。除其他结果外，与没有矢量样物质的模型相比，对带电的希格斯玻色子的敏感性延伸到2个TEV以上。
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.
