A New Massive Type IIA Supergravity From Compactification

TL;DR

This paper derives a novel massive Type IIA supergravity theory through compactification of eleven-dimensional supergravity, introducing a non-trivial Wilson line that results in massive potentials and a cosmological constant.

Contribution

It presents the most general form of eleven-dimensional supersymmetry compatible with on-shell superfields, leading to a new massive supergravity model upon compactification.

Findings

The resulting ten-dimensional supergravity includes massive 1-form and 3-form potentials.

The theory admits a supersymmetric non-static cosmological solution.

It does not possess a supersymmetric eightbrane soliton.

Abstract

We consider the most general form for eleven dimensional supersymmetry compatible with on-shell superfields. This allows for the introduction of a conformal Spin(1,10) connection. In eleven dimensional Minkowski space this modification is trivial and can be removed by a field redefinition, however, upon compactification on S^1 it is possible to introduce a non-trivial `Wilson line'. The resulting ten dimensional supergravity has massive 1-form and 3-form potentials and a cosmological constant. This theory does not possess a supersymmetric eightbrane soliton but it does admit a supersymmetric non-static cosmological solution.
