Abstract

Models predicting the existence of extra spatial dimensions offer compelling and novel solutions to outstanding problems of the Standard Model. In such models, our universe exists on a 4 dimensional brane embedded in a larger dimensional space time. By allowing gravity to propagate in the bulk the gravitational coupling could be comparable with the other gauge interactions thus removing the hierarchy problem. The phenomenology of these models could have dramatic observable effects at the LHC includingthe production and decay of gravitons and mini black holes. In this note we summarize feasibility studies for the discovery of strong gravitational interactions at the LHC.
