Explaining matter/antimatter asymmetries
... In 1972, when the GWS model of weak interactions was still a speculation and even quarks were considered with skepticism, Makoto Kobayashi and Toshihide Maskawa put forward the idea that CP violation originates in the mass mixing of heavy quarks [3]. Quarks were expected to have mass mixing; Cabibbo ...

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.
