Emparan García de Salazar, Roberto A.2010-05-062010-05-0620010556-2821https://hdl.handle.net/2445/12371We obtain a solution describing a gravitational shock wave propagating along a Randall-Sundrum brane. The interest of such a solution is twofold: on the one hand, it is the first exact solution for a localized source on a Randall-Sundrum three-brane. On the other hand, one can use it to study forward scattering at Planckian energies, including the effects of the continuum of Kaluza-Klein modes. We map out the different regimes for the scattering obtained by varying the center-of-mass energy and the impact parameter. We also discuss exact shock waves in ADD scenarios with compact extra dimensions.9 p.application/pdfeng(c) The American Physical Society, 2001Gravetat quànticaTeories del camp unificatRelativitat general (Física)Teoria de Kaluza-KleinQuantum gravityUnified field theoriesRelativitat general (Física)Kaluza-Klein theoriesinfo:eu-repo/semantics/article510713info:eu-repo/semantics/openAccess
