Chiral symmetry breaking in strong interactions

In the early Universe, pressures and temperature prevented the permanent establishment of elementary particles. Even quarks and leptons were unable to form stable objects until the Universe had cooled beyond the supergravity phase At the supergravity symmetry breaking, the Universe passed from the Planck era of total chaos to the era of spacetime foam. Spacetime was acquired during the phase transition. During the GUT symmetry breaking, mass and spacetime separated and particles came into existence After GUT matter forms, the next phase is for GUT matter to decay into lepton and quark matter The weak and electromagnetic fundamental forces seem very different in the present relatively low temperature universe. But when the universe was much hotter so that the equilibrium thermal energy was on the order of 100 GeV, these forces may have appeared to be essentially identical - part of the same unified "electroweak" force Nucleons are 100 times heavier than quarks they are made of. Quarks must get a dynamical mass, and tiiat implies that chirall symmetry of strong interactions must be spontaneously broken. In this study, the first concepts of the Chiral Symmetry were introduced and these concepts were briefly investigated. Key words: Symmetry, symmetry breaking, chrial symmetry, chrial symmetry chrial breaking
