T. D. Lee Colloquium

【T. D. Lee Master Lecture】Fifty Years of Quantum Chromodynamics – The Theory of The Strong Nuclear Force

Description
Abstract

The strong force is one of the four fundamental forces of nature, responsible for binding protons and neutrons together inside the nucleus of an atom. At a more microscopic level, the strong force is the interaction between quarks via gluons, and Quantum Chromodynamics (QCD) is the theory that describes this interaction. 

The theory received a breakthrough in the 1970s when several key figures, including David Gross (the rapporteur), Frank Wilczek (founding director of the Tsung-Dao Lee Institute), and Hugh Politzer, were awarded with the 2004 Nobel Prize for their discovery of the "asymptotically free" nature of QCD. 

Over the past decades, QCD has been subjected to rigorous experimental tests and has led to an increasingly deeper understanding of the microstructure and interaction laws of atomic nuclei and nucleons. In this lecture, Prof. Gross will introduce and discuss the past, present and future of quantum chromodynamics.

Biography
David J. Gross is the Chancellor’s Chair professor of theoretical physics and the former director of the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara. He received his Ph.D. in 1966 from the University of California, Berkeley. Before joining the Kavli Institute, he was the Thomas Jones professor of mathematical physics at Princeton University. Gross was awarded the 2004 Nobel Prize in Physics, along with H. David Politzer and Frank Wilczek, “for the discovery of asymptotic freedom in the theory of the strong interaction.” His other awards include the Sakurai Prize, a MacArthur fellowship, the Dirac Medal, the Oskar Klein Medal, the Harvey Prize, the High Energy and Particle Physics Prize of the European Physical Society, and the Grande Médaille d’Or of the French Academy of Sciences. He holds honorary degrees from institutions in the US, Britain, France, Israel, Argentina, Brazil, Belgium, China, the Philippines and Cambodia. He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, the American Philosophical Society, the Indian Academy of Sciences and the Chinese Academy of Sciences. In 2020, he became Past President of the American Physical Society.
