Technical Report from the year 2012 in the subject Physics - Nuclear Physics, University of Freiburg (Physikalisches Institut), language: English, abstract: This work has been produced during my time at Freiburg University in the division working for the COMPASS collaboration at CERN. Part of their task is to simulate the behaviour of the particles after the collision in the various detectors. The input data is given out by a generator called HepGen and I tested this data against my own calculations using relativistic dynamics. To be able to do so on a large set of data, I wrote a program in C++ that would execute the computing. The appendix "Muon-Proton Collision Simulation" shows the results of a simulation of the behaviour of the outgoing particles after a proton-muon collision as performed in the COMPASS experiment at CERN. The input data is given out by a generator called HepGen and this data was tested against calculations using relativistic dynamics. To be able to do so on a large set of data, a program in C++ was written that would execute the computing.
