ALP Constraints in Gauged $\mathcal{N}=2$ Supergravity

Abstract

We discuss a possibility of restricting parameters in $\mathcal{N}=2$ supergravity based on axion observations. We derive conditions that prepotential and gauge couplings should satisfy. Such conditions not only allow us to constrain the theory but also provide the lower bound of $\mathcal{N}=2\to \mathcal{N}=1$ breaking scale.
