Query: Highly Symmetric D-brane-Anti-D-brane Effective Actions   The entire S-matrix elements of four, five and six point functions of
D-brane-anti D-brane system are explored. To deal with symmetries of string
amplitudes as well as their all order $\alpha'$ corrections we first address a
four point function of one closed string Ramond-Ramond (RR) and two real
tachyons on the world volume of brane-anti brane system. We then focus on
symmetries of string theory as well as universal tachyon expansion to achieve
both string and effective field theory of an RR and three tachyons where the
complete algebraic analysis for the whole S-matrix $<V_{C^{-1}} V_{T^{-1}}
V_{T^{0}}V_{T^{0}} >$ was also revealed. Lastly, we employ all the conformal
field theory techniques to $<V_{C^{-1}} V_{T^{-1}} V_{T^{0}}V_{T^{0}}
V_{T^{0}}>$, working out with symmetries of theory and find out the expansion
for the amplitude to be able to precisely discover all order singularity
structures of D-brane-anti-D-brane effective actions of string theory. Various
remarks about the so called generalized Veneziano amplitude and new string
couplings are elaborated as well.
