I discuss properties of a recently suggested NN interaction Daejeon16 [1]. This interaction is tied to QCD since it is derived from the Idaho NN interaction [2] which has been obtained within the chiral effective field theory in the next-to-next-to-next-to leading order (N3LO) approximation. The Idaho N3LO NN potential was transformed using the Similarity Renormalization Group (SRG) technique to improve the convergence of many-body calculations within various ab initio approaches like the No-core Shell Model (NCSM). Next this SRG-evolved interaction was phase-equivalently transformed to describe binding energies, spectra and other observables in p-shell nuclei without explicit use of three-nucleon (NNN) forces. The Daejeon16 NN interaction is shown to provide a rapid convergence of the NCSM calculations and a very good description of the p-shell nuclei, a more accurate than the previous version of our NN interaction JISP16 [3] reducing the need for NNN forces. This interaction was used to obtain an effective interaction between valence nucleons in the sd shell in the standard shell model with a core using the technique described in Ref. [4] and to calculate resonant states in light nuclear systems, e. g., in the tetraneutron, using the methods suggested in Refs. [5,6]. 1. A.M.Shirokov et al. // Phys. Lett. B. 2016. V. 117. P. 87. 2.
