Abstract :
We present binding energies and properties of wave functions for the light hypernuclei image, image, and image based on realistic hyperon–nucleon and nucleon–nucleon interactions including image conversion. For the solution, the non-relativistic Schrödinger 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 Λ separation energies of image/image.
