We review the color charge degree of freedom in particle physics. Color has two facets in particle physics. One is as a three-valued charge degree of freedom, analogous to electric charge as a degree of freedom in electromagnetism. The other is as a gauge symmetry, analogous to the U(1) gauge theory of electromagnetism. Color as a three-valued charge degree of freedom was introduced by Oscar W. Greenberg [1] in 1964. Color as a gauge symmetry was introduced by Yoichiro Nambu [2] and by Moo… CONTINUE READING
