Hawking Radiation and Phenomenology
General Relativity
The aim of this thesis is to study black hole physics in higher dimensional spacetimes, with a strong emphasis on black hole perturbations in various backgrounds. This will improve the (still incomplete) knowledge of the Hawking evaporation process, which determines the decay of higher dimensional black holes, that could be produced (or excluded) soon, in the 14TeV proton-proton collisions at the CERN, Large Hadron Collider (LHC). This study will contribute greatly to the improvement of the CHARYBDIS2 Monte Carlo event generator (see currently in use by the ATLAS experiment, which simulates the production and decay of such black holes. The Hawking evaporation stage will be improved through analytic and numerical study of the effect of gauge charges, particle mass, asymmetric black hole configurations, higher spins, brane constructions and quantum gravity effects. The construction of the backgrounds themselves and their origin in ultra-relativistic collisions will provide another crucial set of theoretical problems to tackle. These developments, on their own, will help to put bounds or find signatures of the scenario with more confidence. The collaboration within the CHARYBDIS2 development team will benefit from the connection with the ATLAS experimentalists, so that the tools will be adapted to their needs for the analysis of the experimental data. Furthermore, the new phenomenological studies of the effects mentioned above, will result in new ideas for signatures to be used in the experimental searches at the LHC.
