  Based on a four point function, the S-matrix elements at disk level of the
scattering amplitude of one closed string Ramond-Ramond field ($C$), two
tachyons and one scalar field, we find out new couplings in brane anti brane
effective actions for $p=n,p+2=n$ cases. Using the infinite corrections of the
vertex of one RR, one gauge and one scalar field and applying the correct
expansion, it is investigated in detail how we produce the infinite gauge poles
of the amplitude for $p = n$ case. By discovering new higher derivative
corrections of two tachyon-two scalar couplings in brane anti brane systems to
all orders in $\alpha'$, we also obtain the infinite scalar poles in
$t'+s'+u$-channel in field theory. Working with the complete form of the
amplitude with the closed form of the expansion and comparing all the infinite
contact terms of this amplitude, we derive several new Wess-Zumino couplings
with all their infinite higher derivative corrections in the world volume of
brane anti brane systems. In particular, in producing all the infinite scalar
poles of $<V_C V_{\phi} V_T V_T>$, one has to consider the fact that scalar 's
vertex operator in $(-1)$-picture must carry the internal $\sigma_3$ Chan-Paton
matrix. The symmetric trace effective action has a non-zero coupling between
$D\phi^{(1)i}$ and $D\phi^{(2)}_i$ while this coupling does not exist in
ordinary trace effective action.
