Baryon enhancement in jets

The enhancement of the baryon production relative to mesons in small-collision systems is considered a breakthrough result of the Large Hadron Collider since a similar effect in heavy-ion collisions is understood by invoking the formation of the strongly-interacting quark--gluon plasma. In this paper, a baryon enhancement is reported for $p_{\rm T}^{\rm ch,jet}>15$ GeV/$c$ jets produced in pp collisions at $\sqrt{s}=13$ TeV simulated with PYTHIA8. The effect can be explained as a transition between quark-initiated jets (low jet multiplicities) to gluon-initiated jets (high jet multiplicities). The present result contributes to a deeper understanding of the multiplicity dependence of baryon enhancement across different collision systems.
