Description
We discuss the PQ-quality and the possible hierarchical patterns of axion scales (and couplings) for extra-dimensional axions that originate from higher-dimensional p-form gauge fields. As a concrete example, we consider a 5-dim model on Z2-orbifold involving 1-form and 3-form gauge fields, and examine how the warped geometry and fixed-point interactions affect the PQ-quality and axion scale hierarchy.
