We present a systematic investigation of few-nucleon systems and light nuclei using the current Low Energy Nuclear Physics International Collaboration interactions comprising semilocal momentum-space regularized two- and three-nucleon forces up to third chiral order (N2LO). Following our earlier study utilizing the coordinate-space regularized interactions, the two low-energy constants entering the three-body force are determined from the triton binding energy and the differential cross-section minimum in elastic nucleon-deuteron scattering. Predictions are made for selected observables in elastic nucleon-deuteron scattering and in the deuteron breakup reactions, for properties of the A=3 and A=4 nuclei, and for spectra of p-shell nuclei up to A=16. A comprehensive error analysis is performed including an estimation of correlated truncation uncertainties for nuclear spectra. The obtained predictions are generally found to agree with experimental data within errors. Similarly to the coordinate-space regularized chiral interactions at the same order, a systematic overbinding of heavier nuclei is observed, which sets in for A10 and increases with A.

具有半局部动量-空间正则手性相互作用的轻核,直至三阶

我们使用当前的低能核物理国际协作相互作用,包括半局部动量空间正则化的三核力和三核力,直至第三手性级,对少数核子系统和轻核进行了系统的研究(ñ2个大号Ø)。在我们利用坐标空间正则化相互作用进行较早的研究之后,从三重子束缚能和弹性核子-氘核散射的最小横截面最小值确定了进入三体力的两个低能常数。对弹性核子-氘核散射和氘核分解反应中的选定可观察物进行预测,以预测一种=3一种=4 核,并用于 p壳核 一种=16。进行了全面的误差分析,包括对核光谱的相关截断不确定性的估计。通常发现所获得的预测与误差范围内的实验数据相符。类似于相同顺序的坐标空间正则手性相互作用,观察到较重核的系统过量结合,这为一种10 并随着 一种
