Abstract
No conventional picture of nucleus-nucleus collisions has yet been able to explain the abundance of Omega and <(<Omega>)over bar> hadrons in central c ollisions between Pb nuclei at 158A GeV at the CERN SPS. We argue that this is evidence that they art: produced as topological defects arising from th e formation of disoriented chiral condensates with an average domain size o f about 2 fm.
