顶夸克作为重物理学的探测器

Top quarks as a probe for heavy new physics

Celine Degrande

摘要:

最重的费米子预计将与新物理学强烈耦合,因此在许多BSM场景中似乎是一种天然的探针。此外,由于强子对撞机产生的大量顶夸克,先进的实验方法和准确的理论预测,顶级物理学现在已经进入精确时代。在这个演讲中,我们将使用有效场论来寻找一个与模型无关的新物理。这种方法也可以用来量化的空间留给新的物理,如果没有偏离SM被发现。

英文摘要:

The heaviest fermion is expected to couple strongly to new physics and appears therefore as a natural probe in many BSM scenarios. Moreover, top physics has now entered in a precision era thanks to the huge amount of top quarks produced at hadron colliders, advanced experimental methods and accurate theoretical predictions. In this talk, we will used effective field theory to search for heavy new physics in a model independent way. This method can also be used to quantify the room left for new physics if no deviation from the SM is found.
