论文摘要
我们研究超越标准模型物理学将第三代夸克耦合到前两代叶子的效果。我们通过尺寸六的有效运算符参数来参数这些效果，我们还考虑了相关的简化紫外线完成：标量leptoquark和$ w'$型号。我们通过使用与$ W $ Boson相关的单个顶级生产的差异横截面的差异横截面的最新ATLAS测量来得出新的限制，还显示了这些限制如何随未来数据而发展。我们还描述了如何通过使用不同口味的瘦素的差异分布的比率来显着改善限制。
We study effects of beyond the Standard Model physics coupling third generation quarks to leptons of the first two generations. We parametrize these effects by dimension-six effective operators, and we also consider related simplified UV completions: scalar leptoquark and $W'$ models. We derive new constraints on these scenarios by using recent ATLAS measurements of differential cross sections of single top production in association with a $W$ boson, and also show how these limits will evolve with future data. We also describe how the limits can be significantly improved by using ratios of differential distributions with different flavors of leptons.
