Nobel Lecture

The Discovery of Asymptotic Freedom and the Emergence of QCD

David J. Gross held his Nobel Lecture December 8, 2004, at Aula Magna, Stockholm University. He was presented by Professor Sune Svanberg, Chairman of the Nobel Committee for Physics.

Summary: The development of the theory of strong interactions is followed from around 1960 with all the new data available at that time but no theory - to today's description of the strong interaction, Quantum Chromo Dynamics (QCD), a theory that with one single coupling is describing all strong interactions. In contrast to electromagnetic forces, the strong force increases with distance and energy supported by many experiments over the years 1990-2004.
