Figure Caption

Correlations between pairs of $\Xi$ baryons projected in $\Delta\varphi$ in the range $|\Delta y|<1$, comparison between ALICE data and predictions by PYTHIA 8 Monash, PYTHIA 8 Junctions Mode 0, PYTHIA 8 with rope hadronisation, and EPOS LHC. SB = same baryon number, OB = opposite baryon number.

Detail description

Per-trigger yields of $\Xi-\Xi$ pairs (same and opposite baryon number) projected in $\Delta\varphi$ in the range $|\Delta y|<1$. These are measured from minimum-bias collisions using the pp16k+pp18bdefglmop data set, in the $p_\mathrm{T}$ range $1.2<p_\mathrm{T}^\mathrm{trig}<12$ GeV$/c$, $1.2<p_\mathrm{T}^\mathrm{assoc}<12$ GeV$/c$ and using the full detector coverage.

Also included are comparisons to theory predictions by the PYTHIA 8 (Monash tune) and EPOS LHC event generators, which are obtained from the ALICE productions associated with the data set, or in the case of EPOS-LHC only LHC18f1, as well as two extensions to PYTHIA 8: junctions (Mode 0 tune from arXiv:1505.01681) and rope hadronisation (tune provided by Christian Bierlich).
