Effective field theory for Nuclear Halo and Clustering
Prof. Dr. Chen Ji (Wuhan University, China)

Experiments at rare isotope beam facilities have revealed 'halo nuclei' at the edge of the nuclear chart, which are exotic systems featuring a molecular-like structure of a core and halo nucleons. These nuclei play a crucial role in the astrophysical synthesis of elements. Effective field theory (EFT), combined with a nuclear cluster model, provides a robust framework for accurately describing the structure and dynamics of these halos. This talk will cover the fundamentals of halo EFT and demonstrate its application to key observables, including binding energies and radii, as well as essential reaction processes such as photo-disintegration and radiative nucleon captures
