应用弦论

Applied String Theory

Rolf Schimmrigk

摘要：

这是一篇评论。欢迎提出意见。弦论的结构丰富到足以包含标准模型的粗略轮廓，这是一个古老的观察，始于自由场结构、轨道理论，特别是20世纪80年代末和90年代初的卡-丘紧化。当时，这些构造提供了大量不同的真空，有数千个明确构造的卡-丘流形，以及大量玻色子模型的估计，每个模型都与自己的模空间相关联。即使在那时，也很清楚，系统地搜索弦真空景观是不可能的。然而，这不是一个根本性的问题。任何物理学理论不仅要描述我们的宇宙，而且要描述所有可能的相容宇宙，如果采用这种观点，就会导致一种明显的策略，即使用一些唯象学输入，从大量的模型中选择可行的模型，这些模型显然不能描述我们所知道的物理学。

英文摘要：

This is a review. Comments are welcome. The observation that the structure of string theory is rich enough to include the standard model in rough outline is an old one, starting with the early constructions of free field constructions, orbifold theories, and in particular Calabi-Yau compactifications in the late 1980s and early 1990s. At the time these constructions provided a large collection of different vacua, with thousands of explicitly constructed Calabi-Yau manifolds, and estimates of vast numbers of bosonic models, each one associated with its own moduli space. It was clear even then that it would be impossible to systematically search this string vacua landscape. This, however, is not a fundamental problem. Adopting the point of view that any physical theory has to describe not only our universe, but all possible consistent universes, leads to the obvious strategy of using some phenomenological input to select viable models among the ocean of models that obviously do not describe physics as we know it.
