Understanding light nuclei microscopically

Light nuclei are unique laboratories where various many-body approaches can be tested rigorously. Ab initio calculations with few-body nucleonic interactions, such as the No Core Shell Model (NCSM), have been applied successfully to calculate binding energies and spectra of light atomic nuclei (A<20). In ⁴He, various ab initio approaches have been benchmarked against exact few-body calculations.

Weakly-bound and unbound nuclear states in light nuclei can be accurately described using the open quantum system formulation of the nuclear Shell Model, such as the Gamow Shell Model. In parallel to the progress in ab initio theory, there has been a substantial development of Effective Field Theories (EFTs) with the goal of deriving scale-dependent interactions from the underlying Quantum Chromodynamics.
Nowadays, nuclear EFTs are well developed in light nuclei.

This topical two-day meeting will review the status of structure and reactions studies in light nuclei with the emphasis on complementarity between different many-body methods and possible experimental opportunities. We would like to keep the format of the meeting informal and invite those participants who believe they can contribute to the discussion to contact us at fustipen@ganil.fr.
