Abstract
We consider domain walls in the symmetric NMSSM. The spontaneous discrete symmetry breaking produces domain walls, and the stable domain walls are problematic. Thus, we assume the symmetry is slightly but explicitly broken and the domain walls decay. Such a decay causes a large late-time entropy production. We study its cosmological implications on unwanted relics such as moduli, gravitino, LSP and axion.
