Supersymmetry and Non-compact Groups in Supergravity*
We study the interplay of supersymmetry and certain non-compact invariance groups in extended supergravity theories (ESGTs). We use the N = 4 ESGT . to demonstrate that these symmetries do not commute and exhibit the infinite dimensional superinvariance algebra generated by them in the rigid limit. Using this result, we look for unitary representations of the full algebra. We discuss the implic...
متن کاملlocal supersymmetry breaking with surviving compact gauge groups ∗
Generic partial supersymmetry breaking of N = 2 supergravity with zero vacuum energy and with surviving unbroken arbitrary gauge groups is exhibited. Specific examples are given. ∗ Supported in part by EEC Science Program SC1*CT92-0789.
متن کاملSupersymmetry Without Supersymmetry
We present four-dimensional M -theory vacua with N > 0 supersymmetry which, from the perspective of perturbative Type IIA string theory, have N = 0. Such vacua can appear when the compactifying 7-manifold is a U(1) fibration. The missing superpartners are Dirichlet 0-branes. Someone unable to detect Ramond-Ramond charge would thus conclude that these worlds have no unbroken supersymmetry. In pa...
متن کاملSupersymmetry without Supersymmetry
We investigate the possibility that supersymmetry is not a fundamental symmetry of nature, but emerges as an accidental approximate global symmetry at low energies. This can occur if the visible sector is nonsupersymmetric at high scales, but flows toward a strongly-coupled superconformal fixed point at low energies; or, alternatively, if the visible sector is localized near the infrared brane ...
