This is a basic intreoduction to the world of particle physics addressing all physicists and requiring no pre-knowledge on the topic.
After a quick overview on applications of accelerators (HEP, light sources,
medicine and industry), we present with an example how we work with
accelerators in the control room and explain some basic concepts of beam
dynamics in accelerators. The second main goal of these lectures is to
describe the physical principles and key technologies that make possible the
acceleration of charged...
This lecture is focusing on evidences for dark matter in the universe and the axion as one of the prime dark matter candidates. Furthermore, astrophysical motivations for the existence of axions are discussed.
In this lecture different basic approaches for axion search experiments are presented and the ALPS II experiment at DESY, which started data taking in May 2023, is discussed in some detail. In addition, actual PhD theses in the context of ALPS II are
sketched, including opportunities for other direct dark matter searches.
I will give a short introduction in the physics and detection method of
high-energy astrophysics. This includes a discussion of the highest
energetic particles in the Universe, well beyond what can be produced in
man-made accelerators. Mechanism for acceleration, propagation and
interaction of charged cosmic rays, high-energetic gamma rays and neutrinos
are discussed in the context of the...
We will discuss several basic topics in particle physics theory. It
includes, for instance, Lagrangian mechanics, Lorentz transformation,
dimensional analysis, beta decay, Fermi interaction, gauge theory,
electroweak theory, chirality and helicity, spontaneous symmetry breaking,
Higgs mechanism, etc.
In this lecture particle detectors will be introduced starting with a general introduction why and how. This will be followed by the introduction of interaction with matter,
mostly concentrating on charged particles. Terms like ionization, Bethe Bloch multiple scattering and Bremsstrahlung will be introduced.
Once the basics are explained, one of the most important sub-detector type ? the...
The second morning will start out with tracking detectors. What are they for and how does tracking work (very basic). The main technologies such as semiconductor and gas
detectors will be shown including many examples from known experiments. Also Muon detectors as far outside tracking detectors will be covered.
In the last part of the lecture overall concepts, why are large detectors...
Abstract:
Quantum Chromodynamics is the part of the Standard Model
that describes the strong interactions between quarks and
gluons, which bind to protons, neutrons, etc. The lectures
will cover several aspects of this theory, with a focus on
phenomena and methods relevant to collider physics. Where
needed, some background from quantum field theory will be
provided.

In this set of lectures, we will provide an overview of the LHC physics program, focusing on selected results from the last years of operation. We will begin with a general introduction to Standard Model processes, explaining how data is collected at the LHC experiments, and introducing the key concepts required for data analysis. Following that, we will delve into more detailed discussions of...
Plasmas sustain electric fields far in excess of GV/m. These fields can be utilized for
the acceleration of charged particles to ultra-relativistic energies over distances several orders of magnitude shorter than in traditional acceleration schemes based on metallic radio-frequency cavities. Plasma-based electron accelerators rely on the excitation of strong plasma wakefields which can be,...
The „next big thing“ in HEP colliders has still a long way to go. While the
community agrees that the next energy-frontier collider should be a Higgs
Factory, the path towards realisation, the form factor, or even the family
of colliding particles has still to be decided. The path towards very high
collision energies is even less clear and has a lot of technological
challenges to pass. I...
