No conventional picture of nucleus-nucleus collisions has yet been able to explain the abundance of Ω and Ω̄ in central collisions between Pb nuclei at 158 A GeV at the CERN SPS. We argue that such a deviation from predictions of statistical thermal models and numerical simulations is the evidence that they are produced as topological defects in the form of skyrmions arising from the formation of disoriented chiral condensates. The estimated domain size falls in the right range to be consistent with the so far non-observation of disoriented chiral condensate (DCC) from the distribution of neural pions.
