Kappa-symmetric Derivative Corrections to D-brane Dynamics

TL;DR

This paper uses the superembedding formalism to derive kappa-symmetric higher derivative corrections to D-brane dynamics, revealing that corrections appear at even powers of the fundamental length scale and explicitly constructing the first correction related to string amplitudes.

Contribution

It introduces a method to construct manifestly kappa-symmetric higher derivative corrections for D-branes using superembedding formalism, including the first explicit correction term.

Findings

Corrections occur at even powers of the length scale.

Constructed the first kappa-symmetric correction related to open superstring amplitudes.

Demonstrated the applicability of superembedding formalism to D-brane corrections.

Abstract

We show how the superembedding formalism can be applied to construct manifestly kappa-symmetric higher derivative corrections for the D9-brane. We also show that all correction terms appear at even powers of the fundamental length scale $l$. We explicitly construct the first potential correction, which corresponds to the kappa-symmetric version of the $\partial^4 F^4$, which one finds from the four-point amplitude of the open superstring.
