Supersymmetric brane actions from interpolating dualisations

TL;DR

This paper develops a general framework for constructing supersymmetric p-brane actions that interpolate between dual descriptions, applicable to various backgrounds and dimensions, exemplified by a new action for the type IIB NS5-brane.

Contribution

It introduces a novel method for building kappa-symmetric, gauge-invariant brane actions that interpolate between dual formulations without background restrictions.

Findings

Constructed a kappa-symmetric action for the type IIB NS5-brane.

Developed a general interpolation framework for p-brane world-volume theories.

Applied the method to low-dimensional cases and type IIB five-branes.

Abstract

We explore the possibility of constructing p-brane world-volume actions with the requirements of kappa-symmetry and gauge invariance as the only input. In the process, we develop a general framework which leads to actions interpolating between Poincare-dual descriptions of the world-volume theories. The method does not require any restrictions on the on-shell background configurations or on the dimensions of the branes. After some preliminary studies of low-dimensional cases we apply the method to the type IIB five-branes and, in particular, construct a kappa-symmetric action for the type IIB NS5-brane with a world-volume field content reflecting the fact that the D1-, D3- and D5-branes can end on it.
