How big is the proton? - Prof. Dr. Jan C. Bernauer and Prof. Dr. Randolf Pohl

Abstract The proton was discovered 100 years ago, but there is still mystery about some of its basic properties: the proton size has been a puzzle for more than a decade now, after various precision experiments produced incompatible results. The two speakers played a central role in these experiments and will explain the origin story of the puzzle and the current state of attempts to solve it.
