Description
We discuss the stabilization of multiple moduli by utilizing Siegel modular forms
in the framework of $Sp(2g,\mathbb{Z})$ modular invariant theories.
We derive the stationary conditions at CP-conserving fixed points for a generic modular- and CP-invariant scalar potential.
The stabilization of multiple moduli is explicitly demonstrated in $Sp(4,\mathbb{Z})$ and $Sp(6,\mathbb{Z})$ modular invariant scalar potential.
Furthermore, it turns out that there exists a light axion when we incorporate radiative corrections to the scalar potential.
