Dynamics of highly unstable exotic light nuclei and few-body systems

30th January  3rd February 2017          PROGRAM  ProgESNTDynamics_27Jan2017.pdf (updated 27 Jan.)


Organizers: J. Carbonell (IPN Orsay, ), D. Beaumel (IPNO), R. Lazauskas (CNRS/IPHC), E. Hiyama (Strangeness Nuclear Physics Laboratory, RIKEN), F. Miguel Marqués (LPC Caen).


The goals of the project are to discuss and establish the following key points:
1. Relation and efficiency of different ab-initio techniques : Faddeev-Yakubovsky equations, Hyperspherical Harmonics, Gaussian expansion method;
2. Description of the weakly bound and unstable few-particle quantum systems (4n, 5H, 7H, pentaquark,..).
3. Dynamics of the unstable nuclei – key observables, correlations. Reaction mechanisms and models, impact of broad resonances on the experimental observables : description of 4He(8He,8Be)4n reaction using approximate reaction mechanism, ab-initio description of pi-(4He, 4n)pi+ reaction, envisaged in RIKEN and J-PARC experiment aiming to put into evidence 4n resonances.
4. Relation between neutron-rich and proton-rich sector (4H and 4Li, 5H and 5Be...). Signatures of charge symmetry breaking.
