+ | 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++. | ||
