具有稳定模和轻轴子的整体D膜模型

Global D-brane models with stabilised moduli and light axions

Michele Cicoli

摘要:

我们回顾最近的尝试,试图结合全球性的弦紧化问题,如模稳定,与当地的问题,如半现实的D-膜的建设。我们列出了遇到的主要问题,并概述了一个可能的解决方案,允许全球一致的嵌入手性模型。我们还认为,这种稳定机制导致一个axiverse。最后,我们说明了我们的一般要求在一个具体的例子中,卡-丘流形明确描述的复曲面几何。

英文摘要:

We review recent attempts to try to combine global issues of string compactifications, like moduli stabilisation, with local issues, like semi-realistic D-brane constructions. We list the main problems encountered, and outline a possible solution which allows globally consistent embeddings of chiral models. We also argue that this stabilisation mechanism leads to an axiverse. We finally illustrate our general claims in a concrete example where the Calabi-Yau manifold is explicitly described by toric geometry.
