David Gross and Frank Wilczek, and independently H. David Politzer, published their one-loop order Non-Abelian gauge theory results in adjacent 1973 Physical Review Letters papers. Both established a high-energy route to weak coupling; extrapolating into the low-energy region was a separate dynamical problem.[ref]
Ultraviolet Behavior of Non-Abelian Gauge Theories by David J. Gross and Frank Wilczek. 1973, p. 1345, acknowledgment of the independent calculation
[ref]Reliable Perturbative Results for Strong Interactions? by Hugh David Politzer. 1973, p. 1348, low-energy hypotheses versus the asymptotic result
The three shared the 2004 Nobel Prize in Physics for discovering asymptotic freedom in the theory of the strong interaction. David Gross's Nobel lecture describes the unexpected sign and their comparison of independent calculations.[ref]
The discovery of asymptotic freedom and the emergence of QCD by David J. Gross. 2005 reprint, p. 837, award footnote; p. 843, discovery narrative
In his lecture The Dilemma of Attribution, H. David Politzer emphasizes that the prize marks a wider community's work and that a tidy prize-centered history hides how discovery actually proceeds.[ref] Frank Wilczek 2026-10-18

. The 1969 SLAC-MIT deep inelastic electron scattering experiment found approximate Bjorken scaling: an estimated deep-inelastic structure function depended mainly on a ratio of kinematic variables. Its restricted angular coverage did not separately determine both deep-inelastic structure functions, and the extraction assumed transverse virtual photons. This was motivation for a microscopic theory, not already a measurement of the QCD coupling.[ref]
Observed Behavior of Highly Inelastic Electron-Proton Scattering by M. Breidenbach and others. Printed p. 935, abstract; the stated transverse-photon assumption and limited separation of W1 and W2
The 1973 David Gross–Frank Wilczek calculation supplied a quantum field theory explanation of approximately free partons with calculable logarithmic corrections. Asymptotic freedom therefore permits approximate Bjorken scaling without requiring exact scale independence. The QCD coupling governs the corrections, while parton distribution functions and their evolution connect the short-distance calculation to a proton.[ref]
In a later direct test, H1 collided Positrons and protons at HERA and selected deep inelastic scattering events. A liquid-argon particle calorimeter identified the outgoing Positron with an associated track; calorimeter deposits and charged tracks reconstructed particle jets in the Breit frame. Vertex, timing and longitudinal energy-balance cuts suppressed backgrounds; two simulations checked detector corrections. Fits of particle jet cross sections to next-to-leading-order QCD extracted in transverse-energy bins, consistent with decreasing QCD coupling. Hadronization, parton distribution functions and renormalization scale choices limited the inference. This measures rates and fits a coupling, rather than directly reading a force meter.[ref]
