The phase equivalent relativistic NN potential, which is related by a nonlinear equation to the original nonrelativistic potential, is used to construct the mass operator (rest Hamiltonian) of the 3-nucleon system. Employing the CD Bonn NN potential, the solution of the relativistic 3N Faddeev equation for 3 H shows slightly less binding energy than the corresponding nonrelativistic result. The effect of the Wigner spin rotation on the binding is very small.

Coupled Channel

The three-body resonance of [Formula: see text] system is investigated by using the [Formula: see text] coupled channels Faddeev equation. The resonance energy is determined from the pole of S -matrix on the unphysical sheet. It is found that the pole positions of the predicted amplitudes are significantly modified when the three-body dynamics is approximately treated by introducing the effective [Formula: see text] two-body interaction.

Good Agreement

We present an approach to solve the three-nucleon Faddeev equation which avoids the complicated singularity pattern going with the moving logarithmic singularities of the standard approach. Very good agreement of the new and old approaches in the application to nucleon-deuteron elastic scattering and the breakup reaction is found.
