Is anomalous production of omega and omega; evidence for disoriented chiral condensates?
No conventional picture of nucleus-nucleus collisions has yet been able to explain the abundance of Omega and Omega; hadrons in central collisions between Pb nuclei at 158A GeV 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.
