Abstract

In this bachelor's thesis the concept of microscopical black hole production at colliders is investigated. By using extra dimensional models where the value of the Planck mass can be reduced to the TeV scale, gravity can be made stronger at small distances and the Hierarchy problem can be solved. Since gravity is much stronger already at the TeV-scale, there is a possibility that microscopical black holes are produced at the LHC. In this thesis the possibility to produce Quantum Black Holes, black holes with masses around the Planck mass, is implemented in the event generator PYTHIA. Events where the Quantum Black Holes decay into two particles are simulated and studied. A main contribution is successful colour connections between the final states. Something to solve in future simulations is how to give the black holes a spectrum of masses.
