  • Abstract Quantum chromodynamics (QCD), the gauge field theory of strong interaction, has specific features, asymptotic freedom and confinement, which determine the behaviour of quarks and gluons in particle reactions at high and low energy scales. QCD predicts that the strong coupling strength α s decreases with increasing energy or momentum transfer, and vanishes at asymptotically high energies. In this review, the history and status of experimental tests of asymptotic freedom are summarized… CONTINUE READING
