Costa and Joao Penedones (Porto U. | | Abstract: | It is well known that spherical D-branes are nucleated in the presence of an external RR electric field. Using the description of D-branes as solitons of the tachyon field on non-BPS D-branes, we show that the brane nucleation process can be seen as the decay of the tachyon false vacuum. This process can describe the decay of flux-branes in string theory or the decay of quintessence potentials arising in flux compactifications. | | Source: | arXiv, hep-th/0501151 | | Services: | Forum | Review | PDF | Favorites | |
