Answer
Quantum chromodynamics (QCD) is Theory that describes the strong interaction, one of the four fundamental forces of nature. QCD explains how quarks, the fundamental particles that make up protons and neutrons, interact with each other through the exchange of gluons. It is a non-Abelian gauge theory, meaning that the force carrier (the gluon) also interacts with itself.
