Regularized zero-range model and an application to the triton and the hypertriton

Nuclear Theory 2009-11-07 v1

Abstract

We examine the regularized zero-range model in an application to three-fermion systems -- the triton and the hypertriton. We consider bound states and low-energy neutron-deuteron and lambda-deuteron scattering. The model is shown to provide an adequate quantitative description of these system on a par with finite-range potential models. The well known correlation between the doublet ndnd scattering length and the triton binding energy (Phillips line) finds a natural explanation within the model.
