Higher derivative corrections to Wess-Zumino action of Brane-Antibrane systems

TL;DR

This paper explicitly calculates string theory scattering amplitudes to derive higher derivative corrections to the Wess-Zumino action of D-brane-anti-D-brane systems, enhancing understanding of their effective field theory description.

Contribution

It provides the first explicit derivation of higher derivative corrections to the Wess-Zumino action for brane-antibrane systems from string theory amplitudes.

Findings

Derived derivative expansion matching the S-matrix calculations.

Confirmed consistency with known effective actions.

Extended the understanding of brane-antibrane interactions.

Abstract

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.
