Fig. 3: Comparison between data spin correlations with the MC model.
From: Measuring spin correlation between quarks during QCD confinement

Spin correlation \({P}_{{\Lambda }_{1}{\Lambda }_{2}}\) of short-range (a) and long-range (b) \(\Lambda \bar{\Lambda }\), ΛΛ and \(\bar{\Lambda }\,\bar{\Lambda }\) hyperon pairs. The hyperon pair \({P}_{{\Lambda }_{1}{\Lambda }_{2}}\) is compared with \({K}_{{\rm{S}}}^{0}{K}_{{\rm{S}}}^{0}\) measurements and PYTHIA 8.3 predictions. Statistical uncertainties are denoted by the error bars and the systematic uncertainties are represented by the shaded boxes.
