带电和中性希格斯玻色子的六个底夸克信号

Signals with six bottom quarks for charged and neutral Higgs bosons

Radovan Dermisek, Enrico Lunghi, Navin McGinnis, Seodong Shin

摘要:

在具有矢量夸克的两个Higgs二重态模型的扩展中,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,从而导致具有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,因此许多可能的衰变链的共同特征是最终状态中有6个底夸克。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,对带电和中性希格斯玻色子玻色子的灵敏度(延伸到约2 TeV)非常突出。

英文摘要:

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.
