Super D-branes

TL;DR

This paper introduces a comprehensive, Lorentz-invariant, supersymmetric worldvolume action for all type II D-branes in various supergravity backgrounds, unifying and extending previous formulations.

Contribution

It provides a new, unified action formulation for all type II D-branes, including massive backgrounds, with explicit supersymmetry and kappa-invariance, rederived from higher-dimensional theories.

Findings

Constructed a Lorentz-invariant, supersymmetric D-brane action.

Extended the formulation to include massive IIA backgrounds.

Unified description for all p-branes up to p=9.

Abstract

We present a manifestly Lorentz invariant, spacetime supersymmetric, and `$\kappa$-invariant' worldvolume action for all type II Dirichlet p-branes, $p\le9$, in a general type II supergravity background, including massive backgrounds in the IIA case. The $p=0,2$ cases are rederived from D=11. The $p=9$ case provides a supersymmetrization of the D=10 Born-Infeld action.
