| Abstract: The results of a search for CP violation in the production and decay of top quark-antiquark pairs using the semileptonic decay channel are presented. The search uses data from proton-proton collisions at $\sqrt{s}= $ 13 TeV, collected with the CMS detector, corresponding to an integrated luminosity of 137 fb$^{-1}$. Asymmetries that probe CP violating interactions are measured in observables constructed from linearly independent four-momentum vectors associated with the final-state particles. The CP violating effect is evaluated using the measured asymmetries in each observable. The measured effective asymmetries achieved a precision of 10$^{-3}$ and exhibit no evidence for CP violating effects, consistent with the expectation from the standard model. | ||
