Title

The Quest for the Inner Structure of the Proton

Abstract

Exploring the nature of matter has been of central interest over centuries. In order to study the structure of atoms,
protons and neutrons, scattering experiments have become the tool of choice, which have their origin in Rutherford's work in the last century. Since then, the fundamental building blocks of matter were found to be quarks and gluons, which interact through strong interaction. The "Hadron-Electron Ring Anlage" HERA in Hamburg is the latest of the accelerators where scattering experiments probe the proton at higher resolution down to scales well below 10-17m. I will present some of the major results obtained at HERA and discuss the insights gained, most notably about the constituents and the inner structure of the proton. The results of these experiments form an important basis for the exploration of new physics frontiers at the next generation of experiments, like at the LHC.
