当前LHC测量对类矢量夸克的新灵敏度

New sensitivity of current LHC measurements to vector-like quarks

A. Buckley, J. M. Butterworth, L. Corpe, D. Huang, P. Sun

摘要:

具有非手征耦合的夸克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,并且可以通过强相互作用和EM相互作用成对产生,或者通过模型的新耦合单独产生。它们的衰变通常会产生重夸克和规范玻色子,这将有助于在大型强子对撞机上测量各种各样的“标准模型“截面。我们提出了一个研究的敏感性,这样公布的大型强子对撞机测量矢量夸克,首先比较已经从专门的搜索获得的限制,然后扩大到一些迄今未研究的参数区域。

英文摘要:

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.
