On the stability of the classical vacua in a minimal SU(5) five-dimensional supergravity model
- 1. Physics Department, Nuclear and Particle Physics Section, University of Athens, Ilisia, Athens (Greece)
Description
We consider a five-dimensional supergravity model with SU(5) gauge symmetry and the minimal field content. Studying the arising scalar potential we find that the gauging of the U(1)R symmetry of the five-dimensional supergravity causes instabilities. Lifting the instabilities, the vacua are of anti-de-Sitter type and SU(5) is broken along with supersymmetry. Keeping the U(1)R ungauged the potential has flat directions along which supersymmetry is unbroken. (author)
