Research interests

Politzer described the phenomenon of asymptotic freedom: the closer quarks are to each other, the weaker the strong interaction, given by the color charge, will be between them. When quarks are in extreme proximity, the nuclear force between them is so weak that they behave almost like free particles. This result -- independently discovered at around the same time by David Gross and Frank Wilczek at Princeton University -- was extremely important in the development of quantum chromodynamics, the theory of the strong nuclear interactions.
