Heavy-flavour transport: from large to small systems

TL;DR

This paper discusses heavy-flavour particle transport in large and small nuclear collision systems, highlighting new in-medium hadronization models and comparing theoretical predictions with experimental data indicating medium formation in small systems.

Contribution

It introduces an in-medium hadronization model within the POWLANG transport setup and applies it to small systems, expanding understanding of heavy-flavour dynamics across different collision environments.

Findings

Predictions for heavy-flavour production in large systems match experimental data.

Evidence suggests possible medium formation in small systems from recent data.

The in-medium hadronization model improves description of heavy-flavour observables.

Abstract

Predictions for heavy-flavour production in relativistic heavy-ion experiments provided by the POWLANG transport setup, including now also an in-medium hadronization model, are displayed, After showing some representative findings for the Au-Au and Pb-Pb cases, a special focus will be devoted to the results obtained in the small systems formed in proton(deuteron)-nucleus collisions, where recent experimental data suggest the possible formation of a medium featuring a collective behaviour.
