Theoretische Teilchenphysik

What it is about

In this module you will receive a structured overview of the Standard Model of particle physics and central current questions of field theory and phenomenology. In the end you will be able to describe the structure and symmetries of the Standard Model, calculate standard processes with Feynman rules up to one-loop corrections, and explain fundamental aspects of neutrino physics as well as possible extensions beyond the Standard Model.

What you will be able to do

• State the complete Lagrangian density of the Standard Model in writing and explain the terms
• Derive transformation properties under C, P, T and global symmetries and derive conservation laws
• Determine the Feynman rules of the Standard Model and perform perturbative calculations up to one-loop level
• Describe electroweak symmetry breaking via the Higgs mechanism and analyze consequences
• Describe quark mixing with the CKM matrix and derive GIM suppression
• Derive chiral anomalies, gauge anomalies and violation of baryon and lepton number in the SM
• Describe strong CP problem and possible solutions
• Compute CP-violating observables in K- and B-systems and relate to the CKM matrix
• Describe important Higgs production and decay channels at the LHC
• Explain quantum corrections to the Higgs mass/Higgs potential, vacuum stability and the hierarchy problem
• Explain neutrino oscillations, possible neutrino mass terms and the seesaw mechanism
