论文摘要
我们进一步探讨了最近的提议,即QCD中的媒介媒介在各种QCD对象(例如域壁和一个调味的重子)上扮演了Chern-Simons字段的特殊作用。我们计算对域墙理论的贡献,以及来自包括媒介媒介在内的广义Wess-Zumino术语中的Baryon电流。导致预期的Chern-simons项和重子的正确频谱的条件与载体介子优势的条件相吻合。该观察结果为矢量优势的现象学原理提供了理论上的解释,以及将媒介膜鉴定为Chern-Simons领域的实验证据。通过直接从动作中得出Chern-Simons理论,我们获得了有关QCD域壁的新结果。一个结论是,域壁之间存在一阶相变为夸克质量的函数。我们还讨论了我们的结果对胶子和媒介膜之间二元性的应用,并提供了支持双重性的新证据。
We further explore a recent proposal that the vector mesons in QCD have a special role as Chern-Simons fields on various QCD objects such as domain walls and the one flavored baryons. We compute contributions to domain wall theories and to the baryon current coming from a generalized Wess-Zumino term including vector mesons. The conditions that lead to the expected Chern-Simons terms and the correct spectrum of baryons, coincide with the conditions for vector meson dominance. This observation provides a theoretical explanation to the phenomenological principle of vector dominance, as well as an experimental evidence for the identification of vector mesons as the Chern-Simons fields. By deriving the Chern-Simons theories directly from an action, we obtain new results about QCD domain walls. One conclusion is the existence of a first order phase transition between domain walls as a function of the quarks' masses. We also discuss applications of our results to Seiberg duality between gluons and vector mesons and provide new evidence supporting the duality.
