Query: Higher derivative corrections to Wess-Zumino action of Brane-Antibrane
  systems   By explicit calculation, we show that the expansion of the disk level
S-matrix element of one RR field, two open string tachyons and one gauge field
that has been recently found corresponds to the derivative expansion of the
Wess-Zumino action of D-brane-anti-D-brane systems.
