超弦理论中的三点树能级振幅

Three Point Tree Level Amplitude in Superstring Theory

Ehsan Hatefi

摘要:

为了在弦论和场论两方面检验$p=n$情形下无质量三点$(CAA)$振幅的定振幅和精确零结果,以及寻找所有规范场与R-R闭弦的耦合,我们研究了BPS膜世界体积中一个Ramond-Ramond场和两个规范场顶点算符的圆盘级S-矩阵元.

英文摘要:

In order to check the definite amplitude and the exact zero result of the amplitude of three massless points $(CAA)$ in both string theory and field theory side for $p=n$ case and to find all gauge field couplings to R-R closed string, we investigate the disk level S-matrix element of one Ramond-Ramond field and two gauge field vertex operators in the world volume of BPS branes.
