弦现象学的世界表观点

String Phenomenology From a Worldsheet Perspective

Alon E. Faraggi

摘要:

我认为,十维非超对称快子超弦可以作为一个很好的起点,可行的唯象真空的建设。因此,扩大了可能解决弦现象学中一些突出问题的可能解决方案的空间。本文提出了一个无快子的六代类标准模型,它可以看作是$SO(16)\times E_8$杂种优势弦在十维中的轨道折叠。我提出任何四维的$(2,0)$杂合弦都可以通过轨道折叠或插值连接到一个$(2,2)$弦上,并为这个猜想提供了一些证据。它表明,任何不能与$(2,2)$理论相联系的有效场论(EFT)模型都必然处于沼泽地中,这将简化对$(2,0)$弦紧化的模空间的分析。

英文摘要:

I argue that the ten dimensional non--supersymmetric tachyonic superstrings may serve as good starting points for the construction of viable phenomenological vacua. Thus, enlarging the space of possible solutions that may address some of the outstanding problems in string phenomenology. A tachyon free six generation Standard--like Model is presented, which can be regarded as an orbifold of the $SO(16)\times E_8$ heterotic--string in ten dimensions. I propose that any $(2,0)$ heterotic--string in four dimensions can be connected to a $(2,2)$ one via an orbifold or by interpolations and provide some evidence for this conjecture. It suggests that any Effective Field Theory (EFT) model that cannot be connected to a $(2,2)$ theory is necessarily in the swampland, and will simplify the analysis of the moduli spaces of $(2,0)$ string compactifications.
