弦现象学的新观点

Novel Perspectives in String Phenomenology

Alon E Faraggi

摘要:

弦论是当代探索量子力学与引力综合的主要框架。弦现象学旨在研究弦论,同时保持与观测数据的联系。费米子$Z_2\times Z_2$轨道提供了一个案例研究,产生了丰富的空间的唯象模型。十维的弦论产生了非超对称的快子真空,这可能是建立唯象可行模型的良好起点。我将讨论这样一个三代标准模型的一个例子,在这个模型中,除子之外的所有模都被冻结。莫比乌斯对称性可能在量子力学和引力的综合中发挥核心作用。在局部版本中,它在弦论中扮演着核心角色。在一个全球性的版本,它的基础是等价假设的量子力学(EPOQM)形式主义,这意味着空间空间是紧凑的。最近有人提出宇宙微波背景辐射\cite{DiVMS}中存在宇宙封闭的证据。

英文摘要:

String theory is the leading contemporary framework to explore the synthesis of quantum mechanics with gravity. String phenomenology aims to study string theory while maintaining contact with observational data. The fermionic $Z_2\times Z_2$ orbifold provides a case study that yielded a rich space of phenomenological models. String theory in ten dimensions gives rise to non--supersymmetric tachyonic vacua that may serve as good starting points for the construction of phenomenologically viable models. I discuss an example of such a three generation standard--like model in which all the moduli, aside from the dilaton, are frozen. The Möbius symmetry may turn out to play a central role in the synthesis of quantum mechanics and gravity. In a local version it plays a central role in string theory. In a global version it underlies the Equivalence Postulate of Quantum Mechanics (EPOQM) formalism, which implies that spatial space is compact. It was recently proposed that evidence that the universe is closed exists in the Cosmic Microwave Background Radiation \cite{DiVMS}.
