20 Oct 2003 | Journal: | JHEP 0311 (2003) 022 | Subject: | hep-th | Abstract: | We discuss the potential and mass-matrix of gauged N=4 matter coupled supergravity for the case of six matter multiplets, extending previous work by considering the dependence on all scalars. We consider all semi-simple gauge groups and analyse the potential and its first and second derivatives in the origin of the scalar manifold. Although we find in a number of cases an extremum with a positive cosmological constant, these are not stable under fluctuations of all scalar fields. | Source: | arXiv, hep-th/0310187 | Services: | Forum | Review | PDF | Favorites |
