Contribution

It provides the first explicit construction of D=9 supergravity with fermionic terms and introduces novel stainless p-brane solutions that cannot be isotropically oxidized.

Findings

New stainless p-brane solutions preserving half supersymmetry

Explicit supergravity transformation rules with fermionic terms

Identification of solutions that cannot be oxidized to higher dimensions

Abstract

We construct the N=2, D=9 supergravity theory up to the quartic fermionic terms and derive the supersymmetry transformation rules for the fields modulo cubic fermions. We consider a class of p-brane solutions of this theory, the stainless p-branes, which cannot be isotropically oxidized into higher dimensions. The new stainless elementary membrane and elementary particle solutions are found. It is explicitly verified that these solutions preserve half of the supersymmetry.
