It is found that the length of the extra dimension is of physical importance as it determines the decay widths of graviton Kaluza-Klein modes. We show that cosmology as well as collider signals of the Kaluza-Klein modes are very different for different choices of the length of the fifth dimension.9 pages, no figures, a typo in Eq.(15) is fixedHigh Energy Physics - Phenomenologytext
