Light hypernuclei based on chiral interactions
Dr. Andreas Nogga (Forschungszentrum Jülich)

Chiral perturbation theory is a useful tool to develop consistent two- and more-baryon interactions based on the symmetries of Quantum Chromo Dynamics.
In this talk, I especially discuss predictions for the binding energies of the light hypernuclei 3-Lambda- H, 4-Lambda-He and 4-Lambda- H based on chiral hyperon-nucleon interactions.
Especially, I show first results for chiral interactions at next-to-leading order.
These results are used to get a first estimate of possible three-baryon interactions.
The charge-symmetry breaking of 4-Lambda-He and 4-Lambda- H is studied in some detail.
