Description

Few-body dynamics provides a unifying framework that connects modern hadron physics with low-energy nuclear physics. Advances in chiral effective field theory, ab initio nuclear-structure methods, lattice QCD, and the phenomenology of exotic hadrons have brought these traditionally distinct communities into close contact.

This workshop aims to bring together leading theorists working at the frontiers of few-body nuclear and hadron physics to discuss the following topics: chiral EFT and ab initio nuclear physics, cluster effects, exotic nuclei and hadrons, hadronic molecules, lattice QCD for multi-hadron systems, etc.
