Baryon number violation, CP violation and non-equilibrium evolution of the\nearly universe just after the big bang are proposed in the literature to be\nnecessary conditions to explain the observed matter-antimatter asymmetry\n(baryon asymmetry) of the universe. Since the free quarks are not observed and\nthe baryons are formed by the confinement of quarks and gluons, it is necessary\nto understand how the baryons were formed for the first time from the\nnon-equilibrium quarks and gluons in the early universe just after the big bang\nin order to study the baryon asymmetry of the universe. In this paper we study\nthe baryon formation from the non-equilibrium quarks and gluons in the early\nuniverse just after the big bang from the first principle in QCD by using the\nclosed-time path integral formalism in non-equilibrium QCD.\n
