Content:
This lecture focuses on topics of the early universe. After a short review of the history of our universe, we will start our journey with puzzles the Big Bang provides for us and learn how inflation can solve them. We will get to know selected particle physics models that could accommodate such an inflationary epoch. In order to explain our own existence some mechanism had to create the observable baryon asymmetry.
We will get to know different concepts to explain this observation (e.g.
leptogenesis and baryogenesis) and introduce famous models of particle physics that could provide such a mechanism. We will discuss their phenomenology and testability. Naturally, we will also touch neutrino physics at this point and learn about sterile neutrinos. This will bring us also to another important topic of astroparticle physics, namely dark matter. We will discuss different mechanisms (e.g. freeze-out vs
freeze-in) and candidates (e.g. WIMPS, FIMPS, ALPs).
Learning Outcome:
Goal of the lecture is to provide a broad but thorough overview of the current status of theoretical astroparticle physics. After successful completion of the module the students are familiar with the main open questions of astroparticle physics and possible theoretical concepts to solve those (e.g. inflation, leptogenesis, baryogenesis, sterile neutrinos, dark matter). This course will prepare students with the necessary background to carry out supervised research in this field and bridge to current research.
