物理弦系统在$\mathbf{c=26}$倍数上的置换型轨道折叠V.循环置换轨道折叠

The Orbifolds of Permutation-Type as Physical String Systems at Multiples of $\mathbf{c=26}$ V. Cyclic Permutation Orbifolds

M. B. Halpern

摘要:

我认为$\mathbb{Z}_λ,$ $λ$素数自由玻色置换轨道是在$\hat{c} = 26λ$上相互作用的物理弦系统。作为第一步,我介绍扭曲的树图,确认在相互作用的水平,每个扭曲的部门的物理频谱是相当于一个普通的$c=26$封闭字符串。令人惊讶的是,未扭曲的扇区更难理解,而且在缝合环的过程中也有微妙之处,但我能够为完整的模不变宇宙学常数和带有插入的单环图提出临时形式。

英文摘要:

I consider the $\mathbb{Z}_λ,$ $λ$ prime free-bosonic permutation orbifolds as interacting physical string systems at $\hat{c} = 26λ$. As a first step, I introduce twisted tree diagrams which confirm at the interacting level that the physical spectrum of each twisted sector is equivalent to that of an ordinary $c=26$ closed string. The untwisted sectors are surprisingly more difficult to understand, and there are subtleties in the sewing of the loops, but I am able to propose provisional forms for the full modular-invariant cosmological constants and one-loop diagrams with insertions.
