This course introduces you to subatomic physics, i.e. the physics of nuclei and particles. More specifically, the following questions are addressed: - What are the concepts of particle physics and how are they implemented? - What are the properties of atomic nuclei and how can one use them? - How does one accelerate and detect particles and measure their properties? - What does one learn from particle reactions at high energies and particle decays? - How do electromagnetic interactions work and how can one use them? - How do strong interactions work and why are they difficult to understand? - How do weak interactions work and why are they so special? - What is the mass of objects at the subatomic level and how does the Higgs boson intervene? - How does one search for new phenomena beyond the known ones? - What can one learn from particle physics concerning astrophysics and the Universe as a whole? The course is structured in eight modules. Following the first one which introduces our subject, the modules 2 (nuclear physics) and 3 (accelerators and detectors) are rather self contained and can be studied separately. The modules 4 to 6 go into more depth about matter and forces as described by the standard model of particle physics. Module 7 deals with our ways to search for new phenomena. And the last module introduces you to two mysterious components of the Universe, namely Dark Matter and Dark Energy....

Matter and forces, measuring and counting

During this first module, we will give an overview of the objects studied in particle physics, namely matter, forces and space-time. We will discuss how one characterizes the strength of an interaction between particles using the concept of cross section, which is central to our subject. At the end of this module, we will visit the laboratory of the nuclear physics course at University of Geneva to see an example of how one measures the strength of a reaction in practice....

Nuclear physics

During this second module, we deal with nuclear physics and its applications. This is a rather self-contained module. If your main interest is nuclear physics, you will be well served. You will notice that this is a rather substantial module, we recommend that you take two weeks to digest it. At the end of this module, we will visit the Tokamak of the Swiss Institute of Technology in Lausanne and the Beznau nuclear power plant, the oldest one still in operation. This will alllow you to better understand the applications of nuclear physics for our energy supply....

Accelerators and detectors

In this module, we treat the basic facts about particle acceleration and detection. This is a rather self-contained module. If your main interest is particle acceleration and detection, you will be well served. You will notice that this is rather substantial module, we recommend that you take two weeks to digest it. We introduce electromagnetic acceleration and focalisation of particle beams and show how they are used in the accelerator complex of CERN. We describe how charged particles and photons interact with matter and how these interactions are used to detect particles and measure their properties. And we show how modern particle detectors use the synergies between different detection methods to get exhaustive information about the final state of particle collisions....

Electromagnetic interactions

We now start a series of three modules discussing the three fundamental forces described by the Standard Model of particle physics. In this forth module, we go into more details about the properties of electromagnetic interactions. We discuss spin and how it intervenes in measurements. And we give a few examples of basic electromagnetic processes to point out common features. You will notice that the intellectual challenge and also the level of mathematical description rises somewhat as we go along. This is why we first remind you how to describe the intensity of a reaction using the cross section and the decay rate and how to construct a Feynman diagram. ...

Challenging at first for someone with a non-traditional academic background, but thoroughly enjoyable and worth completing, if nothing but for the personal satisfaction of getting through it!

Very interesting course. Quite difficult to pass week 6 due to a question on w boson quark transformation. Couldnt find answers in sylabus. Maybe just me. Overall excellant course.
