Asymptotic freedom

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. Quotes The discovery of asymptotic freedom might make it seem obvious that Feynman diagrams would now litter physicists' scratch pads and blackboards even more densely than before. After all, Dyson had domesticated Feynman's diagrams in the first place as aids for making perturbative calculations. Yet asymptotic freedom did not herald a straight forward return to Dyson's original techniques. For one thing, writing down the so-called Feynman rules proved formidable in the new models.
