Strangeness enhancement across collision systems without a plasma

Christian Bierlich et al.

Summary: We present novel rope hadronization results for the strange hadron enhancement in PP, pPb, and PbPb collisions at LHC energies. Using the rope model for string fragmentation, we observe a coherent increase in strangeness and baryon enhancement across all collision systems as the average charged central multiplicity increases, in agreement with qualitative features of LHC data. In AA collisions, we find that the baryonic yields exceed the data at high multiplicities, and we discuss how a combination of rope hadronization with other string interactions can mitigate this rise.

Setting the string shoving picture in a new frame

Christian Bierlich et al.

Summary: Building on the recent success of the Angantyr model in describing multiplicity distributions in high energy heavy ion collisions, this study investigates the potential of using a string-based scenario to also describe flow effects measured in such collisions. The improved shoving model shows promise in generating flow in AA collisions, but further refinements are needed to match measurements more realistically.

Hadronic rescattering in pA and AA collisions

Christian Bierlich et al.

Summary: The study presents a model for hadronic rescattering which is implemented in Pythia for simulating pp, pA, and AA collisions, showing the impact of rescattering on distributions, space-time evolution, and flow generation. Rescattering is found to significantly contribute to elliptic flow in XeXe and PbPb collisions and has a nontrivial impact on charm production.
