Maths HEP Lunchtime Seminars: Distinguishing Off-Shell Supergravities with On-Shell Physics
30 September 2005 00:00 in CM221
"I will show that it is possible to distinguish between different off-shell completions of supergravity at the on-shell level. I focus on the comparison of the ``new minimal'' formulation of off-shell four-dimensional N=1 supergravity with the ``old minimal'' formulation. In particular there are 3-manifolds which admit supersymmetric compactifications in the new-minimal formulation but which do not admit supersymmetric compactifications in other formulations. Moreover, on manifolds with boundary the new-minimal formulation admits ``singleton modes'' which are absent in other formulations. "
