From: Measuring spin correlation between quarks during QCD confinement

Illustration of tracing the QCD evolution of the spin of a strange quark–antiquark pair to a \(\Lambda \bar{\Lambda }\) hyperon pair and how it can be measured by the STAR experiment at RHIC. See (1)–(5) in the text for details.
