Particle production at LHC energies involves the interplay of hard (perturbative) and soft (non-perturbative) QCD processes. Global observables, such as the charged-particle multiplicity, are related to the initial geometry ...

Heavy quarks, i.e. charm and beauty, are sensitive probes of the medium produced in high-energy heavy-ion collisions. They are produced in the early stage of the collision, mainly in hard partonic scattering processes, and ...

Anisotropic flow is a key observable to characterise the system created in heavy-ion collisions, as it is sensitive to the system’s initial state, transport properties, the equation of state and freeze-out conditions. In ...
