$\Delta\eta$ integrated projection of correlation functions for combined pairs of (left) $\rm p{\Lambda}+\overline{p}\overline{\Lambda}$ and (right) $\rm p\overline{\Lambda}+\overline{p}\Lambda$ obtained from ALICE pp collision data and four Monte Carlo models (PYTHIA6 Perugia-0, PYTHIA6 Perugia-2011, PYTHIA8 Monash, PHOJET) at $\sqrt{s}=7\ \rm{TeV}$. Clear anti-correlation is observed for all baryon pairs. Statistical (bars) and systematic (boxes) uncertainties are plotted.
