Big Bang cosmology and grand unification theories say that the strong force and the electroweak force separated during the electroweak epoch, i.e., $10^{-36}$ to $10^{-32}$ seconds after the Planck epoch. I also read some accounts that say the strong force fields and the electroweak fields separated during the same electroweak epoch. However, since gluon fields do not a appear apart from quarks, then I suppose gluon fields did not arise until the origin of quarks in the quark epoch, i.e., $10^{-12}$ to $10^{-6}$ seconds after the Planck epoch.
If this is the case, then I suppose the strong force separated from the electroweak force during the electroweak epoch; yet no strong force fields arose until the quark epoch. Has anybody proposed this model?
