关于膜-反膜系统的Wess-Zumino项

On Wess-Zumino terms of Brane-Antibrane systems

Mohammad R. Garousi, Ehsan Hatefi

摘要:

在第二类超弦理论中,我们计算了一个闭弦RR场、两个开弦快子和一个规范场的盘级S-矩阵元。我们发现S-矩阵元的一个展开式,它的四个首阶项可由对称迹快子DBI和D-膜-反D-膜系统的Wess-Zumino作用量精确地再现.利用这种一致性,我们还发现了一些WZ项的第一高阶导数校正。

英文摘要:

We calculate the disk level S-matrix element of one closed string RR field, two open string tachyons and one gauge field in type II superstring theory. An expansion for the S-matrix element has been found that its four leading order terms are reproduced exactly by the symmetric trace tachyon DBI and the Wess-Zumino actions of D-brane-anti-D-brane systems. Using this consistency, we have also found the first higher derivative correction to the some of the WZ terms.
