One small correction. In every version of QCD the quarks have
zero rest mass at high temperature. It is only after cooling that the

Of course this is correct. Doesn't Superstring theory itself describe ALL
particles as massless. All excitation states of the strings come in multiples
of the Planck mass with all the particles that we can observe at the lowest
vibration state which is a zero multiple. It would seem all fundamental
theories describe all particles before the symmetry breaking due to the Higgs
field. However this is a very special condition which we can't observe now.
