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++.
