We explore the potential for discovery of an exotic color sextet scalar in same-sign top quark pair production in early running at the LHC. We present the first phenomenological analysis at colliders of color sextet scalars with full top quark spin correlations included. We demonstrate that one can measure the scalar mass, the top quark polarization, and confirm the scalar resonance with 1 fb⁻¹ of integrated luminosity. The top quark polarization can distinguish gauge triplet and singlet scalars.
我们探索了在 LHC 早期运行中，在同号顶夸克对产生中发现奇异色六重标量的可能性。我们展示了第一次在对撞机上进行的包括全顶夸克自旋关联的色六重标量粒子的唯象分析。我们证明了在 1 fb⁻¹积分亮度下，可以测量标量质量、顶夸克极化，并确认标量共振。顶夸克极化可以区分规范三重态和单态标量。
