Abstract

We study anomalous Wess-Zumino-Witten terms associated with the chiral anomaly in dense QCD matter under magnetic fields and rotation. By introducing electromagnetic, baryon number, and isospin background gauge fields, we write down the topological couplings of neutral mesons for the Nf=2 and Nf=3 cases. The resulting terms contain characteristic contributions proportional to B⃗ · ∇⃗ ϕ and Ω⃗ · ∇⃗ ϕ, where ϕ denotes π0, η, or η'. These results are relevant to chiral soliton lattices in dense rotating matter.
