    Results presented in this contribution are obtained within the Low Energy Nuclear Physics International Collaboration (LENPIC). In the project manifesto [1]. it has been stated that LENPIC aims to develop chiral effective field theory nucleon-nucleon and many-nucleon interactions complete through at least fourth order in the chiral expansion (N3LO). Using these interactions, LENPIC's intent is...

    We analyse the behaviour of few-fermion systems having 1/2 spin-isospin symmetryclose to the unitary limit, the limit in which the scattering length takes values much bigger than the typical length of the system. In the case of nucleons, the large values of the singlet and triplet scattering lengths locate the system naturally close to the unitary limit. Using a potential model with variable...

    Recent developments in four-nucleon scattering calculations will be presented. They are based on the Faddeev-Yakubovsky-type equations for transition operators that are solved in the momentum-space partial-wave representation. Their solution is complicated due to the presence of kernel singularities corresponding to open many-cluster channels. This difficulty becomes most evident if ...

    Recently, higher chiral-order nucleon-nucleon potentials have been developed with the chiral effective fields theory [1]. The three-body Faddeev equation had been extended by involving three-body forces [2]. The four-body Yakubovsky equations have also been extended as well [3]. In order to increase the accuracy of not only its two-body forces but also three-body forces, it is indispensable to...
