Light hypernuclei based on chiral and phenomenological interactions

We present binding energies and properties of wave functions for the light hypernuclei H@L3, H@L4, and He@L4 based on realistic hyperon-nucleon and nucleon-nucleon interactions including @L-@S conversion. For the solution, the non-relativistic Schrodinger equation is rewritten into Faddeev or Yakubovsky equations which are solved in momentum space. The accuracy of the numerical calculations is discussed. Based on first leading and next-to-leading order chiral interactions, we discuss the possibility to constrain the hyperon-nucleon interactions by hypernuclear binding energies. Finally, we predict the charge-symmetry breaking of the @L separation energies of H@L4/He@L4.
