47 v 1 2 2 Ju n 19 96 Triton Binding Energy and Minimal Relativity
For relativistic three-body calculations, essentially two different approaches are in use: field theory and relativistic direct interactions. Results for relativistic corrections of the triton binding energy obtained from the two approaches differ even in their sign, which is rather puzzling. In this paper, we discuss the origin of such discrepancy. We show that the use of an invariant two-body...

متن کاملTriton binding energy with realistic statistical uncertainties
We compute the binding energy of triton with realistic statistical errors stemming from NN scattering data uncertainties and the deuteron and obtain Et = −7.638(15) MeV. Setting the numerical precision as Enum t 1 keV we obtain the statistical error Estat t = 15(1) keV which is mainly determined by the channels involving relative S waves. This figure reflects the uncertainty of the input NN dat...
متن کاملRelativistic calculation of the triton binding energy and its implications
First results for the triton binding energy obtained from the relativistic spectator or Gross equation are reported. The Dirac structure of the nucleons is taken into account. Numerical results are presented for a family of realistic OBE models with off-shell scalar couplings. It is shown that these off-shell couplings improve both the fits to the two-body data and the predictions for the bindi...
متن کاملOff-shell Nn Potential and Triton Binding Energy
SUMMARY AND CONCLUSIONS The (nonlocal) Bonn-B potential predicts 8.0 MeV binding energy for the triton (in a charge-dependent 34-channel Faddeev calculation) which is about 0.4 MeV more than the predictions by local NN potentials. We pin down origin and size of the nonlocality in the Bonn potential, in analytic and numeric form. The nonlocality is due to the use of the correct off-shell Feynman...
