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.

当前LHC测量对类矢量夸克的新敏感性

非手性偶合的Quark合作伙伴出现在标准模型的几个扩展中。它们的耦合可能具有非平凡的世代结构，可以通过强相互作用和EM相互作用成对产生，也可以通过模型的新耦合单独产生。它们的衰变通常会产生沉重的夸克和玻色子，这将导致大型强子对撞机的各种“标准模型”横截面的测量。我们介绍了此类已发布的LHC测量对矢量类夸克的敏感性的研究，首先与已经通过专门搜索获得的极限值进行比较，然后将其扩展到迄今为止尚未研究的一些参数区域。
