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.
尚无任何关于核-核碰撞的传统图像能够解释在欧洲核子研究中心超级质子同步加速器（CERN SPS）上，铅核在158A GeV能量下的中心碰撞中大量产生的Ω和Ω⁻ 重子。我们认为，这证明它们是作为拓扑缺陷产生的，这些拓扑缺陷源自平均畴尺寸约为2飞米的非定向手征凝聚体的形成。
