The nucleon-induced deuteron breakup reaction is studied within the Faddeev approach at incoming nucleon laboratory energies of 135 and 200 MeV. The chiral semilocal momentum-space (SMS) potential developed up to N4LO+, supplemented by the N2LO three

Results presented in this contribution are obtained within the Low Energy Nuclear Physics International Collaboration (LENPIC). LENPIC aims to develop chiral nucleon-nucleon and many-nucleon interactions complete through at least the fourth order

We present selected results of theoretical investigations of three-nucleon systems which have been pursued in Kraków for more than thirty years. The Kraków–Bochum group has gathered a lot of experience related to investigations of elastic nucleon

This contribution provides information about correlations among the neutron-proton (np) elastic scattering observables. The most basic prerequisite for this study is existence of models of the nucleon-nucleon (NN) force, for which a covariance matrix

We define a full symmetrizer (antisymmetrizer) $$S_N$$ for a system of N identical bosons (fermions), which can be built recursively as a product of $$(N-1)$$ simple permutation operators $$ (1 + k \epsilon \tau _k)$$ , $$1 \le k < N$$ , and the oper
We demonstrate a computational scheme which drastically decreases the required time to get theoretical predictions based on chiral two- and three-nucleon forces for observables in three-nucleon continuum. For a three-nucleon force containing N short-

The first measurement of the $\stackrel{P\vec}{^{3}\mathrm{He}}(\stackrel{P\vec}{\ensuremath{\gamma}},p)^{2}\mathrm{H}$ process was performed at the High Intensity $\ensuremath{\gamma}$-ray Source ($\mathrm{HI}\ensuremath{\gamma}\mathrm{S}$) facility

We apply a recently developed momentum-space semilocally regularized chiral potential to the $^{2}\mathrm{H}$ and $^{3}\mathrm{He}$ photodisintegration processes and to the (anti)neutrino induced deuteron breakup reactions. Specifically, the differen
We present a perturbative approach to solving the three-nucleon continuum Faddeev equation. This approach is particularly well suited to dealing with variable strengths of contact terms in a chiral three-nucleon force. We use examples of observables

We examine a description of available cross section data for symmetric space star (SST) configurations in the neutron-deuteron (nd) and proton-deuteron (pd) breakup reaction using numerically exact solutions of the three-nucleon (3N) Faddeev equation
