    Abstract

    摘要

    		 In this seminar, I briefly introduce the Faddeev/Yakubovsky and the Jacobi-no core shell model (NCSM) techniques to predict binding energies and other properties of light hypernuclei. Then I use these methods to obtain binding energies for systems with A<=7 for several version of chiral interactions. For the NCSM, a similarity renormalization group (SRG) evolvement of the interactions is necessary. This induces an additional dependence of the results on an SRG parameter which reveals interesting correlations of the binding energies. Finally, I also discuss predictions for the charge-symmetry breaking of these hypernuclei and its relation to Lambda-Sigma conversion that is an integral part of today’s hyperon-nucleon interactions.
