abstract
We present the results from our investigation of angular correlations between baryon pairs in the PYTHIA8 event generator. We show how colour reconnection models and hadronization mechanisms influence such angular correlations and in particular address the effect of gluons on the baryon production mechanism in the Lund string fragmentation model. We conclude by discussing the new theoretical ideas in comparison with the ALICE pp collision results for the baryon angular correlations. We propose a hypothesis for suppressing baryons produced in gluon jets and show how that may influence the angular correlations.

Two-particle number and transverse momentum balance function with event-topology in pp collisions at $\sqrt{s}=13$ TeV
In PYTHIA8 and EPOS-LHC simulations of pp collisions, charge balance function widths narrow with multiplicity, are narrower in jet-like than isotropic events, and EPOS core-on/off differences point to radial flow as the localizing mechanism.
