We investigate four dimensional string theory vacua in view of their validity as unified description of particle physics and cosmology. Parameter scans of phenomenologically allowed regions will be performed, and their scope to accommodate the dark sector of the universe will be tested. The low-energy effective action will be developped further for so far not studied, phenomenologically relevant D-brane configurations, as well as beyond leading order and including instanton effects. Moduli stabilisation will be discussed in the context of new phenomenologically appealing string vacua. The string theory landscape will be constrained by identifying dual string vacua of phenomenological and cosmological interest.

我们研究了四维弦理论真空作为粒子物理和宇宙学统一描述的有效性。将对现象学上允许的区域进行参数扫描，并对其适应宇宙暗区的范围进行测试。低能有效作用将进一步发展到目前为止尚未研究的，现象学上相关的d膜构型，以及超越先导级和包括瞬子效应。模稳定将在新的现象学上吸引人的弦真空的背景下讨论。弦理论的前景将受到现象学和宇宙学兴趣的双弦真空的限制。
