H. David Politzer

H. David Politzer (born the August 31st 1949) is an American physicist . He gained the Nobel Prize of physics 2004, with David Gross and Frank Wilczek for their discovery of a property of the strong Interaction, the asymptotic Liberté, to started from studies undertaken on the Quark S. Since 1978, he is professor with the Caltech.

Politzer was born with New York. It is graduate Bronx High School off Science in 1966, receives its diploma of the Université of Michigan in 1969, and obtains its doctorate with the Université Harvard in 1974. As of its first articles, published in 1973, Politzer describe the asymptotic phenomenon of Liberté by studying the Quark S (ultimate components of the Matière within the framework of the theory of the standard model.). He notices indeed that when the Quark S are very close from/to each other, the nuclear force which is exerted between them is so weak that the quarks behave almost like free particles. This result - which is obtained independently at the same time by David Gross and Frank Wilczek with the Université of Princeton - is extremely important for the development of the quantum Chromodynamique, the theory which describes the strong Interaction.
