3 Dec 2004 | Journal: | Eur.Phys.J. C39 (2005) 249-252 | Subject: | hep-th | Affiliation: | DF/Uel), M. E. X. Guimaraes (MAT/Unb) and V. S. Mendes (DF/Uel | Abstract: | We consider gauge theories based on abelian $p-$forms on real compact hyperbolic spaces. Using the zeta-function regularization method and the trace tensor kernel formula, we determine explicitly an expression for the vacuum energy (Casimir energy) corresponding to skew-symmetric tensor fields. It is shown that the topological component of the Casimir energy for co-exact forms on even-dimensional spaces, associated with the trivial character, is always negative. We infer on the possible cosmological consequences of this result. | Source: | arXiv, hep-th/0501009 | Other source: | [GID 117163] hep-th/0501009 | Services: | Forum | Review | PDF | Favorites |
