摘要
我们考虑这样一种可能性：对于 Intriligator-Seiberg-Shih 模型，具有 Peccei-Quinn 电荷的动力学超对称破缺（DSB）给出 m_{3/2}=O(eV)，由 Nambu-Goldstone 玻色子转化而来的轴子可能成为暗物质候选者，同时 QCD 反常和可观的 \mu 值被自然产生。我们还强调，相当最小的 DSB 内容足以产生观测到的最轻 Higgs 玻色子质量，以及可观 sector 中 sparticles 可接受的软质量。

备注
I would like to thank you for endorsing me. In this study, I considered the possibility that the gravitino problem could be resovled in gauge mediated supersymmetry breaking. In my framework, the QCD axion could become a good cold dark matter candidate, instead of the light gravitino
