Proposals that adress this so called hierarchy problem within the context of brane world scenarios have emerged recently [1]. In these scenarios the Standard Model of particle physics is localised on a three dimensional brane in a higher dimensional space. This raises the exciting possibility that the fundamental Planck scale Mf can be as low as mW . As a consequence, future high energy colliders like LHC could probe the scale of quantum gravity. In this letter we investigate TeV scale gravity associated with black hole production and evaporation at LHC and beyond. One scenario for realizing TeV scale gravity is a brane world in which the Standard Model particles including gauge degrees of freedom reside on a 3-brane within a flat compact space of volume Vd, where d is the number of compactified spatial extra dimensions with radius L. Gravity propagates in both the compact and noncompact dimensions. Let us first characterize black holes in space times with compactified space-like extra dimensions. We can consider two cases:Read More
