Abstract
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.

Report
This new version of the manuscript is completely satisfactory, in the sense that the author has addressed all the points that I had raised. In particular, he has removed some considerations that were perhaps too speculative. On the other hand I think that now the conjectures that he is putting forward, in particular on the relation between the domain walls in QCD at large and small mass respectively, are presented in a better light.
Given that the results and their discussion are stimulating, my recommendation is therefore to publish the manuscript in the present form.
