Phys. Rev. Lett. 86, 4251–4254 (2001)Is Anomalous Production of Ω and Ω̅ Evidence for Disoriented Chiral Condensates?Received 1 December 2000; published in the issue dated 7 May 2001 No conventional picture of nucleus-nucleus collisions has yet been able to explain the abundance of Ω and Ω̅ hadrons in central collisions between Pb nuclei at 158AGeV at the CERN SPS. We argue that this is evidence that they are produced as topological defects arising from the formation of disoriented chiral condensates with an average domain size of about 2 fm. © 2001 The American Physical Society URL:
