Exploring supersymmetric decay chains with regard to future measurements at the LHC

The background of the project is the ongoing search for supersymmetric particles. Today this is one of the main objectives of experiments at particle colliders. The next experimental step, the CERN Large Hadron Collider (LHC), which is expected to begin o peration in 2007, will open up an unprecedented high-energy reach in the search for supersymmetri. The objective for this project is to develop strategies of analysis for supersymmetric particle decay signals at the LHC. Specifically strategies relating to the mSUGRA model of supersymmetry and for specific parameter points in that model. The goal of th ese strategies will be to determine masses for supersymmetric particles, and thereby determine what parameter point is realized. In addition, the possible benefits of input from a future Linear Collider will be studied. Similar strategies are being developed for other models. The ultimate collective goal of these are to serve as a tool for testing the possible realization of supersymmetry in nature. To achieve our objective we will simulate the production of particles at the LHC and the detector by use of computer. The results will be analysed to find methods of reducing backgrounds, and to find statistical methods for determining the masses of super symmetric particles.
