The C P -violating decay rate asymmetry A C P is determined to be ( − 0.44 ± 0.13 ( stat ) ± 0.10 ( syst ) ) % , consistent with zero at 2.7 σ and with the standard model prediction of ( − 0.332 ± 0.006 ) % . This is currently the most precise measurement of this parameter.8 p.application/pdfeng(c) American Physical Society, 2011Física de partículesExperimentsViolació CP (Física nuclear)Particle physicsExperimentsCP violation (Nuclear physics)info:eu-repo/semantics/article6020112019-04-08info:eu-repo/semantics/openAccess
