Fig. 4: Angular dependence of \({\boldsymbol{\Lambda }}\bar{{\boldsymbol{\Lambda }}}\) spin correlations.
From: Measuring spin correlation between quarks during QCD confinement
Spin correlation \({P}_{{\Lambda }_{1}{\Lambda }_{2}}\) as a function of pair separation ΔR. The data are compared with predictions from the SU(6) quark model9 and the Burkardt–Jaffe model27. Statistical uncertainties are denoted by the error bars and the systematic uncertainties are represented by the shaded boxes. The blue and yellow arrows are used to illustrate the separation of the \(\Lambda \bar{\Lambda }\) pairs.
