Towards the understanding of heavy quarks hadronization: from leptonic to heavy-ion collisions

J Altmann, A Dubla, V Greco, A Rossi… - The European Physical …, 2025 - Springer
The formation of hadrons is a fundamental process in nature that can be investigated at
particle colliders. As several recent findings demonstrate, with\(\textrm {e}^{+}\textrm {e}^{-}\) …

String interactions as a source of collective behaviour

C Bierlich - Universe, 2024 - mdpi.com
The discovery of collective effects in small collision systems has spurred a renewed interest
in hadronization models, and is also a source for collective effects all the way to large …

[HTML][HTML] Strangeness enhancement across collision systems without a plasma

C Bierlich, S Chakraborty, G Gustafson, L Lönnblad - Physics Letters B, 2022 - Elsevier
We present novel rope hadronization results for strange hadron enhancement in pp, pPb,
and PbPb collisions using PYTHIA/Angantyr at LHC energies. With the rope model for string …

The dynamic hadronization of charm quarks in heavy-ion collisions

C Bierlich, G Gustafson, L Lönnblad, H Shah - The European Physical …, 2024 - Springer
Abstract The Pythia8/Angantyr model for heavy ion collisions was recently updated with a
mechanism for global colour reconnection. The colour reconnection model used is QCD …

Cluster hadronisation in SHERPA

GS Chahal, F Krauss - SciPost Physics, 2022 - scipost.org
We present the Sherpa cluster hadronization model and a simple model for non-perturbative
colour reconnections. Using two different parton shower implementations we tuned the …

Jet modifications from colour rope formation in dense systems of non-parallel strings

C Bierlich, S Chakraborty, G Gustafson, L Lönnblad - SciPost Physics, 2022 - scipost.org
We revisit our rope model for string fragmentation that has been shown to give a reasonable
description of strangeness and baryon enhancement in high-multiplicity pp events at the …

Develo** the Angantyr model and extending colour reconnection for heavy-ion collisions in Pythia

H Shah - 2023 - portal.research.lu.se
This thesis is composed of four papers, the first two show the attempts made to extend the
Pythia event generator to simulate heavy-ion collision events. The other two papers show …

[PDF][PDF] Improvements to the treatment of gluons within QCD-CR Junctions

T Garnett - 2022 - skands.physics.monash.edu
The mechanisms of hadronisation comprise one of the most important research areas within
modern particle physics, and yet their exact formulation is still not fully developed. This …
