In this paper we have calculated the evolution of chemical composition of the quark-gluon system with 2 + 1 staggered quark flavors, using diagonalquark numbersusceptibilities and the EOS calculated by Wuppertal-Budapest group. Once the evolution the quark-gluon system is available, we can derive ...

To vanhees71: I do not understand why we could not observe "colored particles", let's imagine that there was a small excess of "rod" quarks in the baryogenesis epoch, then after quark decay it should survive only "red" free up quarks that can catch electrons...
We show that a detailed treatment of the equilibrium composition of a quark liquid is crucial to the structure evaluation of its neutrino emissivity. We demonstrate that when massive s-quarks are present in cold quark matter, the electron fraction Y/sub e/ vanishes above a finite baryon density...
