AI总结:

本文在第二类双希格斯二重态模型对齐极限下研究奇异矢量样夸克X和Y的衰变特性,揭示其大的非标准模型衰变率,并通过LHC上的特定特征区分其二重态与三重态表示。

摘要:

我们研究了在双希格斯二重态模型(2HDM)中,分别带5/3和-4/3单位电荷的奇异矢量样夸克(VLQs)$X$和$Y$的衰变。在我们先前对矢量样顶夸克和底夸克(VLT和VLB)研究的基础上,现在我们在第二类汤川结构的对齐极限下研究$X$和$Y$的特性,并表明在这种2HDM框架下,$X$和$Y$态可以具有大的非标准模型(SM)衰变率。我们的分析聚焦于它们在大型强子对撞机(LHC)上的潜在探测,基于它们的成对产生以及随后各种标准模型和非标准模型衰变模式。为了区分VLQs $X$和$Y$的二重态和三重态表示,我们揭示了特定的特征,这些特征可以为这种超越标准模型(BSM)物理的特定架构提供见解。

英文摘要:

We study the decay of the exotic Vector-Like Quarks (VLQs) $X$ and $Y$, with $5/3$ and $-4/3$ units of electric charge, respectively, within the 2-Higgs Doublet Model (2HDM). Building on our previous studies of Vector-Like Top and Bottom (VLT and VLB) quarks, we now investigate the characteristics of $X$ and $Y$ in the alignment limit of a Type-II Yukawa structure and show that, in the framework of such a 2HDM, one can have large non-Standard Model (SM) decay rates of the $X$ and$ Y$ states. Our analysis focuses on their potential detection at the Large Hadron Collider (LHC), based on their pair production followed by a variety of both SM and non-SM decay patterns. In order to distinguish between doublet and triplet representations of the VLQs $X$ and $Y$, we uncover specific signatures that can provide insights into this particular architecture of Beyond the SM (BSM) physics.
