Note on moduli stabilization, supersymmetry breaking and axiverse

Understand

We study properties of moduli stabilization in the four dimensional N = 1 supergravity theory with heavy moduli and would-be saxion-axion multiplets including light string-theoretic axions.

• We give general formulation for the scenario that heavy moduli and saxions are stabilized while axions remain light, assuming that moduli are stabilized near the supersymmetric solution.
• One can find stable vacuum, i.e.
• non-tachyonic saxions, in the non-supersymmetric Minkowski vacua.
