Phenomenology of Randall-Sundrum black holes

We explore the phenomenology of microscopic black holes in the $S^1{/Z}_2$ Randall-Sundrum (RS) model. We consider the canonical framework in which both gauge and matter fields are confined to the brane and only gravity spills into the extra dimension. The model is characterized by two parameters: the mass of the first massive graviton ${(m}_1),$ and the curvature $1/l$ of the RS anti–de Sitter space. We compute the sensitivities of present and future cosmic ray experiments to black hole mediated events, for a wide range of l and $m_1,$ and compare them with the sensitivities of Fermilab Tevatron runs I and II to higher-dimensional physics. As part of our phenomenological analysis, we examine constraints placed on l by AdS-CFT considerations.
