摘要:

ATLAS和CMS在LHC的合作已经对现有的数据集进行了分析,研究了一个矢量类费米子或多重态耦合到标准模型汤川扇区的情况。在不久的将来,随着更多的数据可用,这些实验合作将开始调查更现实的情况。在标准模型的许多扩展中,存在一个以上的额外的矢量样多重态确实是一种常见的情况。这些矢量状多重态之间的相互作用,精密电弱边界,味道和对撞机现象是一个重要的问题,在建立边界或发现物理学超越标准模型。在这项工作中,我们研究的现象学后果的存在下,两个矢量样多重态。我们分析了这种情况下的约束条件,从树级数据和斜校正的情况下混合到每个SM代。在目前的工作中,我们只限于两个顶部的合作伙伴,并没有混合在下行部门的情况下。

英文摘要:

The ATLAS and CMS collaborations at the LHC have performed analyses on the existing data sets, studying the case of one vector-like fermion or multiplet coupling to the standard model Yukawa sector. In the near future, with more data available, these experimental collaborations will start to investigate more realistic cases. The presence of more than one extra vector-like multiplet is indeed a common situation in many extensions of the standard model. The interplay of these vector-like multiplet between precision electroweak bounds, flavour and collider phenomenology is a important question in view of establishing bounds or for the discovery of physics beyond the standard model. In this work we study the phenomenological consequences of the presence of two vector-like multiplets. We analyse the constraints on such scenarios from tree-level data and oblique corrections for the case of mixing to each of the SM generations. In the present work, we limit to scenarios with two top-like partners and no mixing in the down-sector.
