Kaluza-Klein Emission from Cosmic Super-Strings
Dufaux, Jean-Francois (APC, Universite Paris 7)

Cosmic super-strings, fundamental objects of string theory that grow to cosmic size and evolve as a network of cosmic strings, may open a new window to look for observational signatures of string theory, if these signatures can be distinguished from the ones of oridnary (field theory) cosmic strings. One specific aspect of cosmic super-strings is that they interact generically with relatively light and / or strongly coupled Kaluza-Klein modes associated with the geometry of the internal space. In this talk, I will discuss the production of Kaluza-Klein modes by cosmic super-strings, their cosmological consequenses and the resulting constraints on the parameters of cosmic super-strings' networks.
