Anomalous Production of Omega and AntiOmega is Evidence for the Formation of Disoriented Chiral Condensates?
J I Kapusta, S M H Wong
Abstract
No conventional picture of nucleus-nucleus collisions has yet been able to explain the abundance of Omega and AntiOmega hadrons in central collisions between Pb nuclei at 158 A GeV at the CERN SPS. We argue that this is evidence that they are produced from topological defects in the form of skyrmions arising from the formation of disoriented chiral condensates. It is shown that the excess Omega or AntiOmega produced could not be easily washed out in the hadronic medium and therefore would survive in the final state.
