The Cluster of Excellence PRISMA+ addresses the basic questions about the nature of the fundamental building blocks of matter and their importance for the physics of the universe. PRISMA+ consists of renowned research groups that work primarily in the areas of astroparticle, high energy and hadron physics, nuclear chemistry as well as precision physics with ultra-cold neutrons and ion traps. Conducting various new key experiments to study the fundamental forces and limits of the Standard Model is one of the main initiatives of the Cluster.

In a new measurement, the proton once again shows its small side. This is the first time that a new technique has been used. At the same time it is an important test for the theory of QED. Randolf Pohl, Professor of Experimental Atomic Physics at PRISMA+, is involved in this project.
