Phenomenology of Rotating Extra‐Dimensional Black Holes at Hadron Colliders

Results are presented from CHARYBDIS2, a new Monte Carlo simulation of black hole production and decay at hadron colliders. The main new features of CHARYBDIS2 are a full treatment of the spin‐down phase of the decay process using the angular and energy distributions of the associated Hawking radiation, improved modelling of the loss of angular momentum and energy in the production process as well as a wider range of options for the Planck‐scale termination of the decay. The new features allow the study of the effects of black hole rotation and the feasibility of its observation. We present results, with emphasis on the consequences and experimental signatures of black hole rotation at the LHC. The effects of rotation are found to be large, with substantial changes to particle energies and distributions. Rotation persists throughout evaporation, invalidating the approximation of a rapid spin‐down followed by isotropic emission in a non‐rotating Schwarzschild phase. A selection of results are presented from the original article, arXiv:0904:0979.
