我们考虑对称次极小超对称标准模型中的畴壁。自发的离散对称破缺产生畴壁，稳定的畴壁是有问题的.因此，我们假设对称性被轻微但明确地破坏，并且畴壁衰减。这样的衰变导致了大量的后期熵产生。我们研究它的宇宙学意义上不需要的遗物，如模量，引力子，最轻的超粒子，和轴子。
We consider domain walls in thesymmetric next-to-minimal supersymmetric standard model. The spontaneousdiscrete symmetry breaking produces domain walls, and the stable domain walls are problematic. Thus, we assume thesymmetry 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 the moduli, gravitino, lightest superparticle, and axion.
