More on the Standard Model
... Only one fermion can be an any state, which explains most of chemistry…the electrons fill up the energy levels with only one per state. This is the Pauli exclusion principle. But can’t I put two electrons per state? Yes, but their spins are in different directions, so they are not really in the same ...

Production Mechanism of Quark Gluon Plasma in Heavy Ion
... color strings are formed between them. These strings merge to form ‘color rope’ (i.e. CEF is formed). Consequently the production process reduces to the instability of the QCD vacuum in the presence of a classical CEF which is in general space-time dependent.

Strangeness production
Strangeness production is a signature and a diagnostic tool of quark–gluon plasma (or QGP) formation and properties. Unlike up and down quarks, from which everyday matter is made, strange quarks are formed in pair-production processes in collisions between constituents of the plasma. The dominant mechanism of production involves gluons only present when matter has become a quark–gluon plasma. When quark–gluon plasma disassembles into hadrons in a breakup process, the high availability of strange antiquarks helps to produce antimatter containing multiple strange quarks, which is otherwise rarely made. Similar considerations are at present made for the heavier charm flavor, which is made at the beginning of the collision process in the first interactions and is only abundant in the high-energy environments of CERN's Large Hadron Collider.
