Three- and Four-body Structure of S = -2 Hypernuclei
Description
Energy levels of the A = 7 - 10 double Λ hypernuclei are predicted on the basis of an α + x + Λ + Λ four-body model, where x = n,p,d,t,3He and α, respectively. Furthermore, the binding energy of ΛΛ4H is also discussed. We found that the ΛΛ - ΞN coupling is important in the binding energy of ΛΛ4H. Scattering problem of the uudds-barsystem, in the standard non-relativistic quark model is solved for the first time, by treating the large five-body modelspace including the NK scattering channel accurately with the Gaussian expansion method and the Kohn-type coupled-channel variational method
