论文摘要
最近，在手性EFT的框架内开发了新一代的核力量。这些电势的一个重要特征是一种新型的半局部正规化方法，该方法结合了局部调节器长期相互作用的优势，以及在接触相互作用方面的角度无定位调节器的便利性。作者讨论了半本地两种核子电位的关键特征，并通过在EFT扩展中显示出最高第五阶的选定结果来证明其在两个核子领域的出色表现。还审查了较重系统的应用，目前仅限于第三手性命令。该限制反映了构建一致正规化的多体力和当前操作员的概念困难，并影响了所有当前可用的相互作用。作者概述了解决此问题并讨论该领域的未来方向的可能方法。
Recently, a new generation of nuclear forces has been developed in the framework of chiral EFT. An important feature of these potentials is a novel semi-local regularization approach that combines the advantages of a local regulator for long-range interactions with the convenience of an angle-independent nonlocal regulator for contact interactions. The authors discuss the key features of the semi-local two-nucleon potentials and demonstrate their outstanding performance in the two-nucleon sector by showing selected results up to fifth order in the EFT expansion. Also reviewed are applications to heavier systems, which are currently limited to third chiral order. This limitation reflects the conceptual difficulty in constructing a consistently regularized many-body forces and current operators and affects all currently available interactions. The authors outline possible ways to tackle this problem and discuss future directions in the field.
