摘要：

Quantum chromodynamics describes the colour force, which binds quarks and gluons into neutrons and protons, and binds them together in the nuclei of atoms. The colour force is very strong, very short-range (less than 10-16 m) and very complicated — eight different fields respond to the presence and motion of three types of charge, each of which can be positive or negative. Remarkably, we can now observe coherent effects in the colour force, where the fields from two or more particles overlap and reinforce one another.
