In physics, asymptotic freedom is a property of some gauge theories that causes bonds between particles to become asymptotically weaker as energy increases, and distance decreases.
Asymptotic freedom is a feature of quantum chromodynamics (QCD), the quantum field theory of the nuclear interaction between quarks and gluons, the fundamental constituents of nuclear matter. Quarks interact weakly at high energies, allowing perturbative calculations by DGLAP of cross sections in deep inelastic processes of particle physics; and strongly at low energies, preventing the unbinding of baryons (like protons or neutrons with three quarks) or mesons (like pions with two quarks), the composite particles of nuclear matter.
Asymptotic freedom was discovered by Frank Wilczek, David Gross, and David Politzer, who in 2004 shared the Nobel Prize in physics.

Famous quotes containing the word freedom:
“Woe to that nation whose literature is cut short by the intrusion of force. This is not merely interference with freedom of the press but the sealing up of a nation’s heart, the excision of its memory.”
—Alexander Solzhenitsyn (b. 1918)
