在LHC上测量颜色六重态共振的电弱量子数

Measuring Electroweak Quantum Numbers of Color Sextet Resonances at the LHC

Soubhik Kumar, Rafiqul Rahaman, Ritesh K. Singh

AI总结:

本文研究如何在13 TeV LHC上通过同号顶夸克对衰变中底夸克和轻子的角分布及能量分布,区分颜色六重态标量和矢量共振的电弱量子数。

摘要:

我们研究了测量超出标准模型(SM)的颜色六重态粒子电弱量子数的前景,这些粒子衰变为同号顶夸克对。在这些粒子中,颜色六重态标量产生的顶夸克具有相同的手征性,而来自颜色六重态矢量的顶夸克则具有相反的手征性。这一差异被编码在由顶夸克衰变产生的底夸克和轻子的角分布中。我们利用这一特征以及末态喷注和轻子的能量分布来区分三种可能的颜色六重态共振,同时考虑了13 TeV LHC上的各种标准模型背景过程。

英文摘要:

We study the prospect of measuring the electroweak quantum numbers of beyond the Standard Model (SM) color sextet particles that decay into same-sign top quark pairs. Among these particles, the color sextet scalars give rise to top quarks with the same chirality, while the top quarks coming from the color sextet vector would have opposite chirality. This difference gets encoded in the angular distributions of the bottom quarks and leptons originating from the decays of the top quarks. We utilize this feature and the energy distributions of the final state jets and leptons to distinguish among the three possible color sextet resonances, taking into account various SM background processes at the $13$ TeV LHC.
