Humboldt-Universität zu Berlin - Mathematisch-Naturwissen­schaft­liche Fakultät - Experimentelle Elementarteilchenphysik

Z0-Resonanz Praktikum (english)

Deutsche Version

Arbeitsgruppe Experimentelle Elementarteilchenphysik I
Institut für Physik

Winter semester 2018 - Tuesday and Thursday

Attention:  The booking has to be done at least one week before the desired date. Later bookings must be canceled.

The experiment is reserved for groups of maximum 2 people.

Knowledge in the field of particle physics (lecture Kern- und Elementarteilchenphysik) is a basic requirement. Basic knowledge of at least one programming language (Python or ROOT) is an advantage for successful results.

Please contact your tutor by e-mail at least one week before the scheduled experiment day to arrange the exact meeting point and start of the experiment.



The experiment makes use of data recorded with the particle detector L3 at the e+e--accelerator LEP at the European Research Center for Particle Physics CERN in Geneva 1993. It allows to have a basic overiview of the field of work of a particle physicist and to familiarize with the latest analysis methods.

The Praktikum takes place in front of a computer. Please read the literature below carefully and familiarize yourself with the software. Knowledge regarding the following topics is also necessary:

  1. Interaction of particles and matter

  2. Working principle of detectors

  3. Relativistic kinematics

  4. Electroweak coupling

The evaluation will be done with the help of a Python notebook. Basic knowledge of programming is therefore an advantage, otherwise it is expected that the necessary skills are developed independently.



The following literature should be read before the experiment

  1. Overview: Chapter 4 (neutral currents)  of the lecture Experimentelle Elementarteilchenphysik (ps File, pdf File )

  2. L3-experiment: O. Adrinai et al., Results from the L3 Experiment at LEP, Physics Reports 236(1993)1;

    (especially Chapter 2 and Chapter 5)

  3.  H. Schopper, Die Ernte nach einem Jahr LEP-Betrieb, Physikalische Blätter 47(1991)907

  4.  M. Grünewald und T. Hebbecker, Teilchenphysik am e+e--Speicherring LEP, Physikalische Blätter 51(1995)837
