A look into the heart of the proton

Dr. Iris Abt

Protons dominate the visible mass of the universe. They formed right after the big bang and are still there. Even though they have been studied for many years, they still hold a lot of secrets. Why are they so immensely stable? How does their inside (and their outside) really look like? Why does perturbative QCD work at all when used to describe them? Where is their spin hiding? A summary of what we know and do not know about the proton is attempted and the common framework of perturbative QCD introduced.
