Wess-Zumino-Witten Terms of $Sp$ QCD by Bordism Theory

Published 9 Apr 2024 in hep-th and hep-ph | (2404.06185v1)

Abstract: We investigate the four-dimensional Wess-Zumino-Witten (WZW) terms within the framework of $Sp$ quantum chromodynamics (QCD) using invertible field theory through bordism theory. We present a novel approach aimed at circumventing both perturbative and non-perturbative gauge anomalies on spacetime manifolds endowed with spin structures. We study both ungauged and gauged WZW terms including the problems of the topological consistency of gauged WZW terms.
