论文摘要
在带有矢量夸克的两个希格斯双重模型的扩展中，通过带电或中性的希格斯玻色子，级联衰变很容易由矢量样的夸克腐烂占主导地位，从而导致具有6个顶部或底部夸克的签名。由于顶级夸克腐烂也包含底部夸克，因此许多可能的衰减链的常见签名是最终状态下的6个底部夸克。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，与没有矢量类物质的模型相比，对带电和中性的希格斯玻色子的敏感性延伸至2个TEV。
In extensions of two Higgs doublet models with vectorlike quarks, the decays of vectorlike quarks may easily be 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, a common signature for many possible decay chains is 6 bottom quarks in the final state. 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 and neutral Higgs bosons, extending to about 2 TeV, stands out when compared to models without vectorlike matter.
