Particle Physics and Early Universe



This course will discuss how particle physics defines physics of the early universe, the subsequent cosmological scenario and the current state of the universe. Starting with basics of the Standard Model of particle physics (SM), we will see how the whole intricate structure of this theory exhibits itself in a hot and dense, quickly expanding universe. We will demonstrate that this allows to use astrophysical and cosmological observational data to check the SM. The next part will discuss the shortcomings of the Standard Model and different approaches to resolve them: top-down (theory-based) and bottom-up (phenomenology-based), as well as implications of this beyond the SM physics for the early universe (most importantly: the nature of dark matter, dark energy, mechanisms of baryogenesis and inflation).
