Structure of three-body hypernuclei — •Fabian Hildenbrand and Hans-Werner Hammer — Institut für Kernphysik, TU Darmstadt, 64289 Darmstadt, Germany

We construct a short-range effective field theory with contact interactions for three-body hypernuclei in the strangeness S=-1 sector. Renormalization is achieved with a one-parameter three-body force. We present universal correlations between observables in the Isospin I=1 and I=0 sector. Furthermore, predictions for the matter radii in both channels are presented. Finally, we discuss the possibility of a Λnn bound state in this effective theory.
