Halo Physics at the Neutron Drip Line

The description of systems close to the neutron drip line has proven to be one of the most difficult challenges in low-energy nuclear theory and experiment. The large number of scales of different size inherent to this problem complicates a theoretical description with modern ab initio methods. An experimental exploration of this region is difficult due to the short lifetimes of these nuclear states, that are frequently nothing but resonances lying in the positive energy region. However, despite these apparent roadblocks, significant progress has been made both concerning the experimental capabilities and in the ability to calculate continuum properties of states along the neutron drip line, either from first principles or using effective field theories.

This topical program will address recent advances and future possibilities to study halo dynamics in neutron-rich systems. The aim of the program is to bring together experimentalists, that are interested in these exotic systems, with theorists working on the description of threshold features in nuclei along the drip lines. A specific goal is to extend the reach of current theoretical approaches by combining ab initio and effective field theory approaches in a systematic manner. In particular, we intend to identify the most relevant observables and systems to be investigated by future experiments. The program will consist of one workshop and a three-weeks program with daily seminars and discussion sessions.
