A NEW MASSIVE TYPE IIA SUPERGRAVITY FROM COMPACTIFICATION

We consider a more general form for eleven dimensional supersymmetry w hich is still compatible with on-shell superfields. This allows for th e introduction of a conformal Spill(1,10) connection. In eleven dimens ional Minkowski space this modification is trivial and can be removed by a field redefinition, however, upon compactification on S-1 it is p ossible 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 eight-brane soliton but it does admit a supersymmetric non-static cos mological solution. (C) 1998 Elsevier Science B.V.
