-''' Research description: '''
-The Standard Model of particle physics assumes that the world consists of leptons and quarks that
-are elementary particles. However, if they would be made of smaller particles, preons, that would
-explain the leptons and quarks mass hierarchy that we measure. Then leptons and quarks would be
-the lowest energetic states of preon combinations and more higher energy excited states would
-exist.
-We are looking for these excited states using the results of the ATLAS experiment.
-In this bachelor project new variables will be tested which can discriminate between the signal
-and the Standard Model background in events with at least 3 leptons.
-These variables can be used afterwards to increase the sensitivity of the search and to set
-better limits on the model parameters in case no excited leptons are discovered.
-During the project the student will learn to run over MC generator events with a program called
-Rivet, which is based on C++.
