The D-0 mesons are required to originate from semileptonic decays of b hadrons, such that the charge of the muon identifies the flavor of the neutral D meson at production. The asymmetries in the effective decay widths of D-0 and (D) over bar (0) mesons are determined to be A(Gamma)(K+ K-) = (-4.3 +/- 3.6 +/- 0.5) x 10(-4) and A(Gamma) (K+ K- ) = (2.2 +/- 7.0 +/- 0.8) x 10(-4), where the uncertainties are statistical and systematic, respectively. The results are consistent with CP symmetry and, when combined with previous LHCb results, yield A(Gamma) (K+ K-) = (-4.4 +/- 2.3 +/- 0.6) x 10(-4) and A(Gamma) (pi(+)pi(-))= (2.5 +/- 4.3 +/- 0.7) x 10(-4).", optnote="WOS:000506845800002", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=4254), last updated on Fri, 31 Jan 2020 12:29:33 +0000", issn="2470-0010", doi="10.1103/PhysRevD.101.012005", opturl="https://arxiv.org/abs/1911.01114", opturl="https://doi.org/10.1103/PhysRevD.101.012005", language="English" }
