关于非BPS膜的WZ action的进一步讨论

More on WZ action of non-BPS branes

Mohammad R. Garousi, Ehsan Hatefi

摘要:

在非BPS膜的世界体积中计算了一个Ramond-Ramond、两个规范场和一个快子顶点算符的盘级S-矩阵元。然后,我们发现这个振幅的动量膨胀,并表明,无限的快子/无质量极点和接触条款,这个振幅可以复制的快子DBI和WZ的行动,并通过其较高的导数修正。

英文摘要:

We calculate the disk level S-matrix element of one Ramond-Ramond, two gauge fields and one tachyon vertex operators in the world volume of non-BPS branes. We then find the momentum expansion of this amplitude and show that the infinite tachyon/massless poles and the contact terms of this amplitude can be reproduced by the tachyon DBI and the WZ actions, and by their higher derivative corrections.
