Supergravity interacting with bosonic p-branes and local supersymmetry

TL;DR

This paper explores how supergravity interacts with bosonic p-branes, showing that the coupling preserves half of the local supersymmetry when the bosonic brane is derived from a super-p-brane, ensuring a consistent dynamical system.

Contribution

It demonstrates that coupling supergravity with a bosonic p-brane is consistent only if the bosonic brane is the limit of a super-p-brane, preserving half of the local supersymmetry.

Findings

Coupling is self-consistent when bosonic p-brane is a limit of super-p-brane.

Half of the local supersymmetry is preserved in the coupled system.

The interaction maintains the dynamical consistency of the supergravity-bosonic brane system.

Abstract

We study the coupling of supergravity with a purely bosonic brane source (bosonic p-brane). The interaction, described by the sum of their respective actions, is self-consistent if the bosonic p-brane is the pure bosonic limit of a super-p-brane. In that case the dynamical system preserves 1/2 of the local supersymmetry characteristic of the `free' supergravity.
