Abstract
We report a measurement of the difference () between time-integrated -violating asymmetries in and decays reconstructed in the full data set of proton-antiproton collisions collected by the Collider Detector at Fermilab, corresponding to of integrated luminosity. The strong decay is used to identify the charm meson at production as or . We measure , which differs from zero by 2.7 Gaussian standard deviations. This result supports similar evidence for violation in charm-quark decays obtained in proton-proton collisions.
