Related paper Insight into particle production mechanisms via angular correlations of identified particles in pp collisions at $\sqrt{s}=7$ TeV Correlation functions for combined pairs of (left) $\rm p\Lambda+\overline{p}\overline{\Lambda}$ and (right) $\rm p\overline{\Lambda}+\overline{p}\Lambda$. Plots are mirrored around $\Delta\eta=0$.[png] [pdf] [eps]
