We find Im ( z ) = 0.010 ± 0.030 ± 0.013 , Re ( z ) = − 0.065 ± 0.028 ± 0.014 , and | ¯ A / A | = 0.999 ± 0.023 ± 0.017 , in agreement with C P T symmetry.8 p.application/pdfeng(c) American Physical Society, 2016Simetria (Física)HadronsPartícules (Matèria)Symmetry (Physics)HadronsParticlesinfo:eu-repo/semantics/article6697842018-07-16info:eu-repo/semantics/openAccess
