urn:hdl:2445/13244 Pair Creation of Black Holes Joined by Cosmic Strings Emparan García de Salazar, Roberto A. Relativitat (Física) Gravitació (Física) Teoria de camps (Física) Partícules (Física) Estels General relativity and gravitation General theory of fields and particles Stars We argue that production of charged black hole pairs joined by a cosmic string in the presence of a magnetic field can be analyzed using the Ernst metric. The effect of the cosmic string is to pull the black holes towards each other, opposing to the background field. An estimation of the production rate using the Euclidean action shows that the process is suppressed as compared to the formation of black holes without strings. 2010-07-05T08:11:37Z 2010-07-05T08:11:37Z 1995 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció digital del document proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevLett.75.3386 Physical Review Letters, 1995, vol. 75, núm. 19, p. 3386-3389 http://dx.doi.org/10.1103/PhysRevLett.75.3386 (c) American Physical Society, 1995 info:eu-repo/semantics/openAccess American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
