我们探讨右手顶夸克是复合的可能性，识别可能的复合性的签名，以及它们如何在LHC和Tevatron中表现出来。我们进行了一个完整的分析的维度六修改的顶部耦合胶子，并发现在t率的运营商之间的取消允许非常低的复合尺度，但这可以大大提高通过看运动学分布。转向LHC，我们研究了从六维四顶算符产生的四顶产物，并估计收集光度为100 fb−1的LHC对高达5 TeV的复合性尺度敏感。
We explore the possibility that the right-handed top quark is composite, identifying possible signatures of compositeness and how they might manifest themselves at the LHC and Tevatron. We perform a complete analysis of the dimension six modifications of the top coupling to gluons and find that cancellations among operators in the t rate allow for very low compositeness scales, but this can be drastically improved by looking at kinematic distributions. Turning to the LHC, we examine four top production from a dimension six four-top operator and estimate the LHC with 100 fb−1 collected luminosity to be sensitive to compositeness scales as high as 5 TeV.
