QCD challenges from pp to AA collisions

The 4th edition of the workshop series  “International Workshop on QCD Challenges from pp to AA collisions” will be held in Padova between 13th and 17th February 2023.

About sixty experimental and theoretical physicists will gather together and discuss open questions on various features of the strong interaction and Quantum Chromodynamics (QCD), the theory describing it in the Standard Model of Particle Physics.

The strong interaction binds together protons and neutrons in atomic nuclei, as well as more fundamental objects, quarks, inside protons and neutrons. Though QCD was developed in the 1960s, several of its consequences have not been yet understood completely, especially when the theory is applied to describe the production and the interactions of particles in complex systems, with implications that range from particle and nuclear physics to cosmic-ray physics, astrophysics, and the evolution of the Early Universe.

The workshop is organized in plenary and round-table sessions related to the following six discussion tracks:

Initial-state and ultra-peripheral
Jet production and properties in pp and in the medium
Event properties and hydro in small and large systems
Hadronization of light and heavy flavour across collision systems
Energy loss and transport in the medium and in small system
QCD and astrophysics

The event is organised by the INFN Padua Division and the Department of Physics and Astronomy of the Padua University.
