Various methods have been discussed to find the terms of tree level low energy abelian open superstring effective action with derivative corrections. In this thesis, we will focus on the open superstring tree level sacttering amplitude calculation one. We would try to understand this method up to the six-point function in the hope of reaching a crucial machinery which could help to evaluate the scattering amplitude for any value of N. The main aim of this thesis is to maximize the usefulness of this method to construct generally the nonabelian generalization of this action and particularly the nonabelian Born-Infeld theory up to possible order in field strength.
