弦论中$\barΩ$的解耦

The Decoupling of $\barΩ$ in String Theory

K. S. Narain, A. Zein Assi

摘要:

本文利用$\barΩ$研究拓扑弦的形变。也就是说,采用微扰弦振幅的方法,我们确定的$\barΩ$ -变形的一个物理状态的斯汀频谱。我们计算的拓扑振幅$F_g$在杂化弦论在后者的存在。特别是,我们表明,它是至关重要的,包括二次项的有效行动,以$\barΩ$解耦。事实证明,这种退耦发生在整个弦的水平,这表明这是非微扰的。

英文摘要:

In this note, we study the deformation of the topological string by $\barΩ$. Namely, adopting the perturbative string amplitudes approach, we identify the $\barΩ$-deformation in terms of a physical state in the sting spectrum. We calculate the topological amplitudes $F_g$ in heterotic string theory in the presence of the latter. In particular, we show that it is crucial to include quadratic terms in the effective action in order for $\barΩ$ to decouple. It turns out that this decoupling happens at the full string level, suggesting that this holds non-perturbatively.
