论文摘要
宇宙常数和电气层次结构问题一直是研究的巨大灵感。然而，从低能量有效的领域理论家的角度来看，这两个自然问题的解决仍然是神秘的。弦理论景观和可能的基于字符串的多元宇宙提供了部分答案，但由于技术和概念原因，它们也引起了争议。本讲义，适用于一个学期课程或进行自学，试图为这些主题提供技术介绍。他们的目标是在量子场理论和一般相对论方面具有扎实背景的研究生和研究人员，他们希望在合理的技术层面上了解弦乐景观及其与层次结构问题和自然性的关系。弦理论的必要基础是课程的一部分。本文还将使正在更深入研究弦理论的研究生受益。在这种情况下，本注释可以作为超出正式弦理论课程的额外阅读。
The cosmological constant and electroweak hierarchy problem have been a great inspiration for research. Nevertheless, the resolution of these two naturalness problems remains mysterious from the perspective of a low-energy effective field theorist. The string theory landscape and a possible string-based multiverse offer partial answers, but they are also controversial for both technical and conceptual reasons. The present lecture notes, suitable for a one-semester course or for self-study, attempt to provide a technical introduction to these subjects. They are aimed at graduate students and researchers with a solid background in quantum field theory and general relativity who would like to understand the string landscape and its relation to hierarchy problems and naturalness at a reasonably technical level. Necessary basics of string theory are introduced as part of the course. This text will also benefit graduate students who are in the process of studying string theory at a deeper level. In this case, the present notes may serve as additional reading beyond a formal string theory course.
