Using the known value of αΛ, and assuming that ᾱΛ=-αΛ, ᾱΩ=[-1.81±0.28(stat)±0.26(syst)]×10-2. A comparison between this measurement of ᾱΩᾱΛ and recent measurements of αΩαΛ made by HyperCP shows no evidence of a violation of CP symmetry. © 2006 The American Physical Society.text::journal::journal article::research article
