Resumen

A search for (Formula presented) violation in (Formula presented) and (Formula presented) decays is presented using the full Run 1 and Run 2 data samples of (Formula presented) collisions collected with the LHCb detector, corresponding to an integrated luminosity of (Formula presented) at center-of-mass energies of 7, 8, and 13 TeV. For the Run 2 data sample, the (Formula presented)-violating asymmetries are measured to be (Formula presented) and (Formula presented), where the first uncertainty is statistical and the second is systematic. Following significant improvements in the evaluation of systematic uncertainties compared to the previous LHCb measurement, the Run 1 dataset is reanalyzed to update the corresponding results. When combining the Run 2 and updated Run 1 measurements, the final results are found to be (Formula presented) and (Formula presented), constituting the most precise measurements of these asymmetries to date.
