The three-baryon $ΛNN$ potential
Abstract
Description
Using a three-baryon $ΛNN$ potential having a spin-independent dispersive and a two-pion exchange components, realistic variational Monte Carlo calculations have been performed for the $Λ$-seperation energy for $^{5}_Λ$He. A relationship between strengths associated with both pieces of $ΛNN$ force giving exact experimental $Λ$-seperation energy has been obtained which then combined with our previous study on $^{17}_{\,\,Λ}$O hypernucleus determines a unique and acceptable set of strength parameters for $ΛNN$ potential. The $ΛNN$ force is found important for the core polarization.
