The flavor of the charm meson is inferred from the charge of the pion in D*(+) -> D-0 pi(+) and D*(-) -> (D) over bar (0)pi(-) decays. The difference between the CP asymmetries in D-0 -> K-K+ and D-0 -> pi(-)pi(+) decays, Delta A(CP) A(CP)(K-K+) - A(CP)(pi(-)pi(+)), is measured to be [-0.10 +/- 0.08(stat) +/- 0.03(syst)]%. This is the most precise measurement of a time-integrated CP asymmetry in the charm sector from a single experiment.application/pdfengcc-by (c) CERN, 2016http://creativecommons.org/licenses/by/3.0/esMesons (Física nuclear)Violació CP (Física nuclear)Simetria (Física)Mesons (Nuclear physics)CP violation (Nuclear physics)Symmetry (Physics)info:eu-repo/semantics/article6693302017-07-27info:eu-repo/semantics/openAccess27232015
