10 Apr 1995 | | Journal: | Phys.Rev. D52 (1995) 2254-2265 | | Subject: | gr-qc hep-th | | Abstract: | We investigate the pair creation of charged black holes in a background with a positive cosmological constant. We consider $C$ metrics with a cosmological constant, and show that the conical singularities in the metric only disappear when it reduces to the Reissner-Nordström de Sitter metric. We construct an instanton describing the pair production of extreme black holes and an instanton describing the pair production of non-extreme black holes from the Reissner-Nordström de Sitter metric, and calculate their actions. There are a number of striking similarities between these instantons and the Ernst instantons, which describe pair production in a background electromagnetic field. We also observe that the type I instanton in the ordinary $C$ metric with zero cosmological constant is actually the Reissner-Nordström solution. | | Source: | arXiv, gr-qc/9504015 | | Services: | Forum | Review | PDF | Favorites | |
