This paper presents a comprehensive review of both the theory and experimental successes
of Quantum Chromodynamics, starting with its emergence as a well defined theory in 1972-
73 and following developments and results up to the present day. Topics include a review of
the earliest theoretical and experimental foundations; the fundamental constants of QCD; an
introductory discussion of lattice QCD, the only known method for obtaining exact
predictions from QCD; methods for approximating QCD, with special focus on effective field …

Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers”,
is reviewed; the goal of this review is to provide advanced Ph. D. students a comprehensive
handbook, helpful for their research. When QCD was “discovered” 50 years ago, the idea
that quarks could exist, but not be observed, left most physicists unconvinced. Then, with the
discovery of charmonium in 1974 and the explanation of its excited states using the Cornell …
