Relative magnitude and phase information is determined, and coherence factors and related observables are computed for both the whole phase space and a restricted region of 100     MeV / c 2 around the K ∗ ( 892 ) ± resonance. Two formulations for the K π   S -wave are used, both of which give a good description of the data. The ratio of branching fractions B ( D 0 → K 0 S K + π − ) / B ( D 0 → K 0 S K − π + ) is measured to be 0.655 ± 0.004 ( stat ) ± 0.006 ( syst ) over the full phase space and 0.370 ± 0.003 ( stat ) ± 0.012 ( syst ) in the restricted region. A search for C P violation is performed using the amplitude models and no significant effect is found. Predictions from SU(3) flavor symmetry for K ∗ ( 892 ) K amplitudes of different charges are compared with the amplitude model results.1 p.application/pdfeng(c) American Physical Society, 2016HadronsMesons (Física nuclear)HadronsMesons (Nuclear physics)info:eu-repo/semantics/article6697012018-07-16info:eu-repo/semantics/openAccess
