Probing C P T Invariance with Top Quarks at the LHC

Year: 2024

Type: article

Abstract: 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.
