A stable hierarchy from Casimir forces and the holographic interpretation | | Jaume Garriga

19 Dec 2002 | | Journal: | Phys.Lett. B560 (2003) 91-97 | | Subject: | hep-th gr-qc hep-ph | | Abstract: | We show that in the Randall-Sundrum model the Casimir energy of bulk gauge fields (or any of their supersymmetric relatives) has contributions that depend logarithmically on the radion. These contributions satisfactorily stabilize the radion, generating a large hierarchy of scales without fine-tuning. The logarithmic behaviour can be understood, in a 4D holographic description, as the running of gauge couplings with the infrared cut-off scale. | | Source: | arXiv, hep-th/0212227 | | Services: | Forum | Review | PDF | Favorites | |
