Content

Effective Field Theories (EFTs) furnish an elegant means to take the first step towards the next quantum field theory of nature, because they allow to include physics beyond the standard model (SM) in a model-independent way via higher dimensional operators.
Beyond that, they are useful to tackle problems with separated scales, that arise in many areas of fundamental physics. EFTs allow to describe the important physics conveniently in terms of degrees of freedom that are most relevant at a given length-scale. In particular, they allow to consistently re-sum large logarithms of ratios of scales, that would otherwise spoil the perturbative expansion, and provide a modern notion of renormalization.
This lecture provides a comprehensive introduction to the concept of EFTs and modern applications, including the bottom-up approach to physics beyond the SM as a guide to the next theory of nature.

The topics covered include:
- General concept of EFTs and resummation
- EFT of weak interactions: Fermi-Theory and Flavor Physics
- EFT of QCD: Chiral Perturbation Theory
- EFTs and Electroweak Symmetry Breaking: the non-linear Sigma Model
- EFT of Axions / Axion-like particles
- EFTs and neutrino physics
- Bottom-up approach to a more fundamental theory of nature: SM-EFT and its variants
- EFT for Dark Matter

In diesem Seminar wollen wir Schlüsselexperimente besprechen, die unser heutiges Bild der Elementarteilchenphysik und insbesondere das Standardmodell der Elementarteilchlchenphysik geprägt haben. Die Experimente reichen von der Entdeckung des Myon-Neutrinos bis zur Entdeckung des Higgs-Bosons durch die ATLAS und CMS Kollaborationen in 2012 und die aktuellen Messungen zur Bestimmung der Neutrino-Masse durch die KATRIN-Kollaboration aus dem Jahr 2021.

Themen: Die Entdeckung des Myon-Neutrinos, 
Entdeckung der Kernspaltung,  Die Entdeckung des J/psi und Quarkonium Spektroskopie, Die Helizität des Neutrinos: das Goldhaber Experiment, Entdeckung der CP-Verletzung im Kaon-System, Entdeckung der Gluonen, Entdeckung der elektroschwachen Eichbosonen, Solare Neutrinos und SNO, Messung von (g-2) des Myons, Bestimmung der Übergangstemperatur zum Quark-Gluon-Plasma, Entdeckung des Higgs-Bosons, Bestimmung der Neutrino-Masse

Astronomical and cosmological observations require the existence of dark matter in our universe. Today, Dark Matter is generally thought to have particle nature, where the dark matter particles have relatively long lifetimes, interact gravitationally and, possibly, also via the weak interaction.

In the Standard Model of particle physics, only neutrinos have the correct properties, but, due to their small mass, neutrinos can only account for a small fraction of the observed Dark Matter in our universe. In extended versions of the standard model sterile neutrinos, in particular keV-sterile neutrinos can contribute as warm dark matter candidates.

Light supersymmetric particles are an example for weakly interacting massive particles (WIMPs) which are candidates for cold darm matter. Other viable dark matter candidates are axions, which have been introduced to solve the strong CP-problem of QCD, or axion-like particles.

The seminar will address the astrophysical and cosmological evidences which led to the postulation of dark matter. It will discuss the most prominent dark matter candidates and the different direct and indirect methods to search for their existence. Particular emphasis is put on the determination of neutrino masses, the search for sterile neutrinos, WIMPS and axions.
