The first model-independent sensitivity to CPT violation in the top-quark sector is extracted from ATLAS and CMS measurements of the top and antitop kinematical mass difference. We find that the temporal component of a CPT-violating background field interacting with the top-quark vector current is restricted within the interval [−0.13,0.29] GeV at 95% confidence level.

用 LHC 的 Top Quarks 探测 CPT 不变性

第一个与模型无关的对顶夸克扇区中 CPT 违规的敏感性是从顶部和反顶部运动质量差异的 ATLAS 和 CMS 测量中提取的。我们发现，在 95% 置信水平下，违反 CPT 的背景场与顶夸克矢量电流相互作用的时间分量被限制在区间 [−0.13,0.29] GeV 内。美国物理学会 2024 年出版
