Abstract
Knowledge of all-αⲠhigher derivative corrections to leading order BPS and non-BPS brane actions would serve in future endeavor of determining the complete form of the non-abelian BPS and tachyonic effective actions. In this paper, we note that there is a universality in the all-αⲠorder corrections to BPS and non-BPS branes. We compute amplitudes between one Ramond-Ramond C-field vertex operator and several SYM gauge/scalar vertex operators. Specifically, we evaluate in closed form string correlators of two-point amplitudes ACÏ, ACA, a three-point amplitude ACÏÏ, and a four-point amplitude ACÏÏÏ. We carry out pole and contact term analysis. In particular we reproduce some of the contact terms and the infinite massless poles of ACÏÏÏ by SYM vertices obtained through the universality.
