The question of how the high-temperature phase of strongly interacting matter, the quark gluon plasma, transitions into the hadronic phase at the pseudo-critical temperature is a central motivation of heavy-ion collider experiments at the RHIC and LHC facilities. This project aims to shed light on the process of hadronization. We do this within the framework of the hadron resonance gas model to study interactions between light flavour hadrons, to understand the formation of loosely bound (anti-)(hyper-)nuclei, and to study formation of hadrons with open and hidden heavy flavour. Using data on quarkonium and heavy quark production and Drell-Yan dilepton production in pA and AA collisions, the influence of nuclear structure of parton distributions will be studied and nuclear PDFs will be determined.

强相互作用物质的高温相夸克胶子等离子体在伪临界温度下如何转变为强子相的问题是在RHIC和LHC设施进行重离子对撞机实验的主要动机。这个项目旨在阐明强子化的过程。我们在强子共振气体模型的框架内进行这项工作，以研究轻味强子之间的相互作用，理解松散束缚(反)(超)核的形成，并研究具有开放和隐藏重味道的强子的形成。利用PA和AA碰撞中夸克和重夸克的产生以及Drell-yan双轻子产生的数据，研究了核结构对部分子分布的影响，并确定了核PDF。
