D-膜作用中曲率项的T-对偶性

T-duality of curvature terms in D-brane actions

Mohammad R. Garousi

摘要:

我们研究了已知的曲率项的DBI部分的D-膜作用下的T-对偶变换。利用作用量与线性阶T-对偶标准规则的相容性作为指导原则,我们在作用量中包含了适当的NS-NS $B$ -场项,并证明它们再现了相应盘级散射振幅的O(N '^2)项。

英文摘要:

We examine the known curvature terms in the DBI part of the D-brane action under the T-duality transformation. Using the compatibility of the action with the standard rules of T-duality at the linear order as a guiding principle, we include the appropriate NS-NS $B$-field terms in the action and show that they reproduce the O(α'^2) terms of the corresponding disk-level scattering amplitude.
