Präzisionsexperimente in der Teilchenphysik bei niedrigen Energien
Precision Experiments in Particle Physics at Low Energies

This course gives an introduction to precision experiments on particle physics and fundamental forces, which are not performed at collider experiments at particle accelerators. The course gives an introduction to the underlying physics motivation of such modern experiments and highlights their complementarity to searches for new physics at colliders. A focus of the course are the wide range of experimental techniques, which involve methods form atomic and molecular physics, particle and nuclear physics, and condensed matter physics.

The course covers:

• Precision tests of the Standard Model of particle physics, including
• Electric Dipole Moments
• studies of the weak interaction
• Search for dark matter candidates
• Neutrinos and their properties
• Searches for hypothetical new short-range forces
• Test of fundamental assumptions like Lorentz-invariance

After successful participation in this module, the student is able to

1. Understand the concepts of modern precision particle physics experiments
2. Discuss precision measurements
3. Explain the evidence, motivation and experimental searches for different dark matter candidates
4. Discuss and understand the latest results from neutrino physics

Keine Vorkenntnisse nötig, die über die Zulassungsvoraussetzungen zum Masterstudium hinausgehen.

Grundkenntnisse in Kern- und Teilchenphysik auf dem Bachelor Niveau [PH0016 oder vergleichbar].

The lecture presents the learning content in consecutive topical blocks. Modern experiments are discussed on the basis of original publications and extensive cross references to latest results are provided. Short summaries of a number of related experiments are prepared and presented by the students in flash presentations.

The lecture coninuously offers the possibility for intensive discssions of the topics of the course and thematically related questions that arise from the referenced material.

Blackboard, PowerPoint, Multimedia presentation.

Website for presentation material, additional literature and links.

All original literature articles are handed out in the course.

Es findet eine mündliche Prüfung von 25 Minuten Dauer statt. Darin wird das Erreichen der im Abschnitt Lernergebnisse dargestellten Kompetenzen mindestens in der dort angegebenen Erkenntnisstufe exemplarisch durch Verständnisfragen und Beispielrechnungen überprüft.

Prüfungsaufgabe könnte beispielsweise sein:

• Was ist der experimentelle Nachweis, dass Neutrinos Masse besitzen?
• Wie erreichen Präzisionsversuche Sensitivität über das Standardmodell der Teilchenphysik hinaus?
• Beschreiben sie die experimentelle Technik, die typischerweise zur Messung des Elektrischen Dipolmoments verwendet wird.
• Wie könnten WIMPS im Labor nachgewiesen werden?
• Wie testet man experimentell die Lorentz-Invarianz?
