Special Challenges in Quantum Chromodynamics

This workshop focuses on advanced topics in perturbative Quantum Chromodynamics (QCD), inspired by  the scientific legacy of Stefano Catani

The central theme of this year's edition is Sudakov resummation. We plan to critically compare different resummation approaches, calculations in direct and conjugate spaces, in Soft Collinear Effective Theory (SCET) and direct QCD, parton showers and automated resummation techniques. Additionally, we will discuss the impact of resummation on heavy-quark fragmentation and shape variables in e+e- annihilation, and its relevance for the accurate determination of the strong coupling.
