Vector dominance, one flavored baryons, and QCD domain walls from the "hidden" Wess-Zumino term
TLDR
In this article, it was shown 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.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.read more

Pseudo-Conformal Sound Speed in the Core of Compact Stars
TL;DR: By implementing the putative "hadron-quark continuity" conjectured in QCD in terms of skyrmion-half-skyrmions topological change in an effective field theory for dense matter, this article argued that (quasi-)baryons could "masquerade" deconfined quarks in the interior of compact stars.

Consequences of anomalous ward identities
TL;DR: In this paper, the anomalous Ward identities are shown to satisfy consistency or integrability relations, which restrict their possible form, for the case of SU(3) × SU(1) and for SU(2) + SU (3) + 2.
