Book: Particle Physics on the Eve of LHC: Proceedings of the Thirteenth Lomonosov Conference on Elementary Particle Physics
Publisher: World Scientific Publishing
This proceedings volume is devoted to a wide variety of items, both in theory and experiment, of particle physics such as tests of the Standard Model and beyond, physics at the future accelerators, neutrino and astroparticle physics, heavy quark physics, non-perturbative QCD, quantum gravity effects and cosmology. It is important that the papers in this volume reveal the present status and new developments in the above-mentioned items on the eve of a new era that starts with the Large Hadron Collider (LHC).At present, the dominant point of view is that all physical phenomena and processes, both terrestrial and cosmological, are governed by three fundamental forces: gravitational, electroweak and chromodynamic. The color charge serves as the source of chromo dynamic forces. In this talk we shall expose the main stages of the early development of the hypothesis of the quantum number of color and of colored quarks, put forward under the ideological influence of and in collaboration with N .Bogolubov at the JINR Laboratory of Theoretical Physics. In these works, the concept of color, colored quarks, was introduced for the first time, and a dynamical description of hadrons was given within the framework of the model of quasifree colored quarks.Introduction of the quantum number of color permitted to treat colored quarks as real physical objects, constituents of matter. Further, from the color 5U(3) symmetry, the Yang-Mills principle of local invariance and quantization of chromo dynamic fields gave rise to quantum chromo dynamics – the modern theory of strong interactions.
