A dedicated summer school at a remote location outside of Mainz will be organized every two years, aiming to bridge the gap between experiment and the basic theory of the particle physics. Renowned theory speakers are invited for lecture series, which will give particular emphasis to be accessible for an audience of students with a background in experimental physics. For instance, the lectures will cover basic techniques from theory, e.g. the calculation of simple Feynman diagrams and estimation methods to quantify the size or the impact of certain fundamental reactions. Such skills are of particular importance for experimentalists to assess early on if a certain experimental approach has a chance of success. Moreover, introductory lectures on modern theory tools like Monte Carlo event generators, that are frequently used by theorists and experimentalists will give given.
