论文摘要
具有非手续耦合的Quark合作伙伴出现在标准模型的几个扩展中。它们可能具有非平凡的世代结构，可以通过强和EM相互作用成对产生，也可以通过模型的新耦合而单独产生。他们的衰变通常会产生沉重的夸克和仪表玻色子，这将有助于LHC的各种已经测量的“标准模型”横截面。我们介绍了此类已发表的LHC测量对矢量样夸克的敏感性的研究，首先是与已经从专用搜索获得的限制进行比较，然后扩展到某些SO-FAR未研究的未研究的参数区域。
Quark partners with non-chiral couplings appear in several extensions of the Standard Model. They may have non-trivial generational structure to their couplings, and may be produced either in pairs via the strong and EM interactions, or singly via the new couplings of the model. Their decays often produce heavy quarks and gauge bosons, which will contribute to a variety of already-measured "Standard Model" cross-sections at the LHC. We present a study of the sensitivity of such published LHC measurements to vector-like quarks, first comparing to limits already obtained from dedicated searches, and then broadening to some so-far unstudied parameter regions.
