Abstract
A search for charge-parity () violation in Cabibbo-suppressed , , and decays is reported using proton-proton collision data, corresponding to an integrated luminosity of , collected at a center-of-mass energy of 13 TeV with the LHCb detector. High-yield samples of kinematically and topologically similar Cabibbo-favored decays are analyzed to subtract nuisance asymmetries due to production and detection effects, including those induced by violation in the neutral kaon system. The results are where the first uncertainties are statistical and the second systematic. They are the most precise measurements of these quantities to date, and are consistent with symmetry. A combination with previous LHCb measurements, based on data collected at 7 and 8 TeV, is also reported.
