关于D-膜action的$ α'^2$阶

On D-brane action at order $ α'^2$

Ali Jalali, Mohammad R. Garousi

摘要:

我们利用D-膜作用量与线性T-对偶、S-对偶和S-矩阵元的相容性作为指导原则,在II型超弦理论中寻找$α'^2$阶的一个无质量闭弦和两个开弦的所有世界体积耦合.特别地,我们发现第二基本形式的平方只出现在世界体积曲率中,并通过变换$\hat{R}_{μν}\rightarrow \hat{R}_{μν}+\nabla_μ\nabla_νΦ$证实了弦框架作用中出现的观察。

英文摘要:

We use compatibility of D-brane action with linear T-duality, S-duality and with S-matrix elements as guiding principles to find all world volume couplings of one massless closed and two open strings at order $α'^2$ in type II superstring theories. In particular, we find that the squares of second fundamental form appear only in world volume curvatures, and confirm the observation that dilaton appears in string frame action via the transformation $\hat{R}_{μν}\rightarrow \hat{R}_{μν}+\nabla_μ\nabla_νΦ$.
