The International Conference on Hard and Electromagnetic Probes of High-Energy Nuclear Collisions (HARD PROBES 2023) will be held at Aschaffenburg (Germany) from March 26th to 31st, 2023. This is the 11th of the Hard Probes conference series. The conference is focused on experimental and theoretical developments on perturbative probes of hot and dense QCD matter as studied in high-energy nucleus-nucleus, proton-nucleus and proton-proton collisions.
