Current research in Quantum Chromodynamics (QCD) focuses on understanding the phases of strongly interacting matter and their cosmic roles, the internal structure of nucleons, and the properties predicted by QCD. Key problems include the transition of quarks and gluons into pions and nucleons, and the significance of gluons and their self-interactions within nucleons and nuclei. Researchers are also investigating the fundamental features of QCD and their connections to gravity and spacetime. Advances in computational power have revitalized interest in Lattice QCD, which has been a significant area of study since the early 1980s. For further information, resources like the NSAC long-range plan and the Nuclear Physics European Collaboration Committee can provide valuable insights.
