Abstract
In order to check the definite amplitude and the exact zero result of the amplitude of three massless points in both string theory and field theory side for 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.
