Prof. Dr. Skyler Degenkolb Prof. Dr. Ulrich Uwer Prof. Dr. Tilman Plehn Lectures: INF 227, HS2 Thursdays, 09:15 - 11:00, Fridays, 09:15 - 11:00. Lectures will start on 16 April. Tutorials: Thursday afternoon, will start on 23 April The written examination will take place on Thursday, 23 July 2026, from 09:00 to 11:00 in Philosophenweg 12, gHS. As the exam starts at 09:00 sharp, please make sure to arrive a few minutes earlier. You are also required to bring your student identity card for identification. To be admitted to the written examination, 60% of the points of the exercise sheets are required. Admissions to the exam from previous years are not accepted. Registration for the exam via heiCO is open until Thursday, 16 July 2026, 23:59. Please make sure to register in time. In order to be eligible for the retry exam, you must either participate in the main exam or provide a valid excuse for non-attendance. Please note: Only a pen, one double-sided DIN A4 cheat sheet (handwritten or printed), and a non-internet-capable calculator are permitted. The use of books, additional notes (except for the permitted cheat sheet), or any electronic devices other than the calculator is obviously not allowed.

The lecture focuses on modern particle physics. It builds on the letcure Particle Physics and replaces the former lecture Standard Model.

Topics of the lecture:  While the lecture Particle Physics was mainly focused on tree-level processes, the lecture Particle Physics II adresses the effects of higher-order (radiative) quantum corrections - often called loops. The lecture comprises three theoretical blocks (DGLAP evolution in QCD, Higgs mechanism, Beyond the Standard Model) and several experimental blocks (higher order QED effects, quark and lepton flavor physics, neutron physics, dark matter searches).

Prerequisites:   Lecture "Particle Physics".
