David Gross

David J. Gross is an American theoretical physicist who shared the 2004 Nobel Prize in Physics for discovering asymptotic freedom in the strong interaction.

Frank Wilczek: Frank Wilczek is an American theoretical physicist who shared the 2004 Nobel Prize in Physics for discovering asymptotic freedom. Wilczek coauthored the 1973 paper with Gross that established asymptotic freedom.
Asymptotic freedom: The property that quarks interact more weakly at shorter distances or higher energies. Gross shared the Nobel Prize for discovering this behavior in the strong interaction.
Princeton University: A private research university in Princeton, New Jersey, founded in 1746. Gross was a graduate student there when he began research on the strong interaction.
Deep inelastic scattering: A process in which high-energy particles probe the internal structure of protons or neutrons. Its scaling behavior helped motivate the search for a theory with asymptotic freedom.
Quantum chromodynamics: The quantum field theory describing the strong interaction between quarks and gluons. Asymptotic freedom helped establish it as the theory of the strong interaction.
H. David Politzer: H. David Politzer is an American theoretical physicist who shared the 2004 Nobel Prize in Physics for discovering asymptotic freedom. Politzer independently discovered asymptotic freedom in 1973 and shared the prize with Gross and Wilczek.
Quark: A fundamental particle that combines with other quarks through the strong interaction. The weakening of the force at short distances lets quarks behave nearly freely.
Harvard University: A private research university in Cambridge, Massachusetts, founded in 1636. Gross earned his doctorate there under theoretical physicist Sheldon Glashow.
Parton model: A model treating a fast-moving hadron as a collection of nearly free constituents called partons. Asymptotic freedom explains why partons appear nearly free during high-energy scattering.
Grand unified theory: A theoretical framework that combines the strong, weak, and electromagnetic interactions at high energies. Gross later helped develop theories seeking to unify the fundamental interactions.
