402-0715-00L | Low Energy Particle Physics | W | 6 credits | 2V + 1U | A. S. Antognini, P. A. Schmidt-Wellenburg | |

Abstract | Low energy particle physics provides complementary information to high energy physics with colliders. In this lecture, we will concentrate on flagship experiments which have significantly improved our understanding of particle physics today, concentrating mainly on precision experiments with neutrons, muons and exotic atoms. | |||||

Objective | You will be able to present and discuss: - the principle of the experiments - the underlying technique and methods - the context and the impact of these experiments on particle physics | |||||

Content | Low energy particle physics provides complementary information to high energy physics with colliders. At the Large Hadron Collider one directly searches for new particles at energies up to the TeV range. In a complementary way, low energy particle physics indirectly probes the existence of such particles and provides constraints for "new physics", making use of high precision and high intensities. Besides the sensitivity to effects related with new physics (e.g. lepton flavor violation, symmetry violations, CPT tests, search for electric dipole moments, new low mass exchange bosons etc.), low energy physics provides the best test of QED (electron g-2), the best tests of bound-state QED (atomic physics and exotic atoms), precise determinations of fundamental constants, information about the CKM matrix, precise information on the weak and strong force even in the non-perturbative regime etc. Starting from a general introduction on high intensity/high precision particle physics and the main characteristics of muons and neutrons and their production, we will then focus on the discussion of fundamental problems and ground-breaking experiments: - search for rare decays and charged lepton flavor violation - electric dipole moments and CP violation - spectroscopy of exotic atoms and symmetries of the standard model - what atomic physics can do for particle physics and vice versa - neutron decay and primordial nucleosynthesis - atomic clock - Penning traps - Ramsey spectroscopy - Spin manipulation - neutron-matter interaction - ultra-cold neutron production - various techniques: detectors, cryogenics, particle beams, laser cooling.... | |||||

402-0393-00L | Theoretical Cosmology and Different Aspects of GravityDoes not take place this semester. | W | 8 credits | 4V | L. Heisenberg | |

Abstract | These lecture series will be dedicated to different advanced topics within the framework of theoretical cosmology and gravity. A detailed introduction into the successful construction of General Relativity and beyond will be given, together with their cosmological implications. | |||||

Objective | These lecture series will discuss different advanced topics within the framework of theoretical cosmology and gravity. First of all, I will give a detailed introduction into the successful construction of General Relativity from a geometrical perspective. After constructing our geometrical setup I will discuss the most general space-time geometries and their different manifestations. This will also allow me to introduce the geometrical trinity of gravity, in which the same theory of General Relativity can be constructed a la Einstein based on curvature, a la TEGR based on torsion and a la CGR based on non-metricity, which represents a simpler formulation of General Relativity. Starting from the defining key properties of General Relativity I will explain in which consistent ways these properties can be altered. Still following the geometrical interpretation of gravity this will allow me to introduce modifications of gravity based on affine structure. In the second part I will abandon the geometrical framework and adapt to the field theory perspective. In this context I will construct General Relativity as the unique fundamental theory for a massless spin-2 field. This means that any modification of gravity will ultimately introduce additional degrees of freedom in the gravity sector. After discussing the building blocks of field theories, I will introduce massive gravity, Horndeski scalar-tensor theories, generalized Proca theories and scalar-vector-tensor theories. Based on the assumption that General Relativity is the underlying theory of gravity I will introduce the standard model of cosmology and discuss the tenacious challenges we are facing within this framework. We will study the FLRW models relevant for inflation and late-time universe at the background level and consider small cosmological perturbations together with their evolution. We will see how we can use different observational channels and theoretical consistency checks in order to critically assess different gravity theories. In this context we will pay special attention to the implications of gravitational waves measurements for generalizations of gravity theory beyond General Relativity. Using specialized Mathematica packages some of the relevant relations and computations will be illustrated as well. | |||||
