I'm currently studying from "Particle Astrophysics" by Perkins.
On page 132 it says:
After $kT$ fell below the strong quantum chromodynamics (QCD) scale parameter ∼ $200$ MeV, the remaining quarks, antiquarks, and gluons would no longer exist as separate components of a plasma but as quark bound states, forming the lighter hadrons such as pions and nucleons.
On page 148 it says:
In the early stages of the Big Bang, when the thermal energy per particle $kT$ was large compared with the hadron masses, it is expected that many types of hadrons, including protons and neutrons and their antiparticles, would have been in thermal equilibrium with radiation, being created and annihilated in reversible reactions such as $$p+\bar p \leftrightarrow \gamma+\gamma$$
The second quote implies $kT \gg 1$ GeV, but the top quote says that at this temperature there was a quark-gluon plasma.
What nuance am I missing?
