5.4 Color and strong interactions

In this module we discuss the structure of hadrons and the properties of strong interactions. We start out by explaining how one uses the scattering of electrons off nucleons to learn about the internal structure of these baryons. Step by step we lead you from elastic scattering, through the excitation of resonances, all the way to deep inelastic processes. You thus learn about the concept of form factors and structure functions and what they tell us about hadron structure. We then discuss the physics behind this and learn about color and the strange features of strong interactions, like asymptotic freedom and confinement.
