“…To summarize, we obtain very promising results for a broad range of few-and many-nucleon observables at N 2 LO of the chiral expansion. In the future, we plan to extend these studies beyond this chiral order [32,[95][96][97][98][99][100][101][102], see Refs. [61,103] for first steps along these lines, which will allow us to improve the accuracy of our predictions and perform more stringent tests of the theoretical framework.…”

We present calculations of nucleon-deuteron scattering as well as ground and low-lying excited states of light nuclei in the mass range A=3-16 up through next-to-next-to-leading order in chiral effective field theory using semilocal coordinate-space regularized two-and three-nucleon forces. It is shown that both of the low-energy constants entering the three-nucleon force at this order can be determined from the triton binding energy and the differential cross section minimum in elastic nucleon-deuteron scattering. From all considered nucleon-deuteron scattering observables, the strongest constraint on these low-energy constants emerges from the precisely measured cross section minimum at EN = 70 MeV. The inclusion of the three-nucleon force is found to improve the agreement with the data for most of the considered observables.

“…Up to and including N 4 LO, the nuclear Hamiltonian includes the contributions of the 3NF and four-nucleon forces, most of which have already been worked out [42,43,44,45,46,47,48,49,50,51,52,53]. The numerical implementation of the 3NF in Faddeev-Yakubovsky equations and in most of the ab-initio methods for nuclear structure calculations requires performing partial wave decomposition (PWD) which represents a non-trivial task.…”

“…It remains to be seen upon the inclusion of the 3NF and performing complete calculations whether the A y -puzzle will survive at higher orders of the chiral expansion. Notice further that at N 4 LO, the 3NF involves purely short-range contributions with two derivatives, which affect nucleon-deuteron (Nd) P-waves [62]. It is conceivable that the inclusion of such terms will lead to a proper description of A y once the corresponding LECs are tuned to reproduce Nd scattering observables.…”

We employ a variety of ab initio methods including Faddeev-Yakubovsky equations, No-Core Configuration Interaction Approach, Coupled-Cluster Theory and In-Medium Similarity Renormalization Group to perform a comprehensive analysis of the nucleon-deuteron elastic and breakup reactions and selected properties of light and medium-mass nuclei up to 48 Ca using the recently constructed semilocal coordinate-space regularized chiral nucleon-nucleon potentials. We compare the results with those based on selected phenomenological and chiral EFT two-nucleon potentials, discuss the convergence pattern of the chiral expansion and estimate the achievable theoretical accuracy at various chiral orders using the novel approach to quantify truncation errors of the chiral expansion without relying on cutoff variation. We also address the robustness of this method and explore alternative ways to estimate the theoretical uncertainty from the truncation of the chiral expansion.
