THE QUANTUM NUMBER COLOR, COLORED QUARKS AND QCD (Dedicated to the 40th anniversary of the discovery of cоlоr) V. А. Matveev, A. N. Tavkhelidze А brief review is given of the priority works which were mainly carried out at the Laboratory of Theoretical Physics, JINR, and devoted to the introduction to hadron physics of the concept of color and colored quarks, and to the description of hadrons in the framework of the model of quasi-free quarks. These ideas play а key role in the modern theory of strong interactions - quantum chromodynamics. |
