“…We are not aware of a regular paper from the Teheran group about their treatment of N d scattering in 3D, although photodisintegration of 3 H based on realistic NN interactions with full inclusion of final state interactions among the outgoing nucleons reported in [88], requires the same technical achievements as N d scattering.…”

We discuss the application of the chiral N 3 LO forces to three-nucleon reactions and point to the challenges which will have to be addressed. Present approaches to solve three-nucleon Faddeev equations are based on a partial-wave decomposition. A rapid increase of the number of terms contributing to the chiral threenucleon force when increasing the order of the chiral expansion from N 2 LO to N 3 LO forced us to develop a fast and effective method of automatized partial wave decomposition. At low energies of the incoming nucleon below ≈ 20 MeV, where only a limited number of partial waves is required, this method allowed us to perform calculations of reactions in the three-nucleon continuum using N 3 LO two-and three-nucleon forces. It turns out that inclusion of consistent chiral interactions, with relativistic 1/m corrections and short-range 2π-contact term omitted in the N 3 LO three-nucleon force, does not explain the long standing low energy A y -puzzle. We discuss problems arising when chiral forces are applied at higher energies, where large three-nucleon force effects are expected. It seems plausible that at higher energies, due to a rapid increase of a number of partial waves required to reach convergent results, a three-dimensional formulation of the Faddeev equations which avoids partial-wave decomposition is desirable.

“…It should be clear that this approach is more efficient for scattering problems, especially in the energy regions where the PW-based calculations have slow convergence. The formulation of 3N scattering and 3 H photodisintegration in a realistic 3D approach has been done successfully [37]- [38] and the calculation is underway. Molecular, atomic, and nuclear or subnuclear physics are but a few examples of various fields of physics where quantum mechanical few-body problems play an important role.…”

A recently developed three-dimensional approach (without partial-wave decomposition) is considered to investigate solutions of Faddeev-Yakubovsky integral equations in momentum space for three-and four-body bound states, with the inclusion of three-body forces. In the calculations of the binding energies, spin-dependent nucleon-nucleon (NN) potential models [soft-core potential S3, Malfliet-Tjon (MT) I-III, Yamaguchi-type potentials (YS), and P 5.5 -model of Gibson-Lehman (P 55 GL)] are considered along with the scalar two-meson exchange three-body potential. The presently reported results agree well with the ones obtained by other techniques, demonstrating the advantage of an approach in which the formalism is much more simplified and easy to manage for direct computation.
