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.File in questo prodotto:
