从手征有效拉格朗日到原子核结构的漫长而曲折的道路
The long and winding road from chiral effective Lagrangians to nuclear structure
摘要:
我回顾了核物理的手征动力学。在第一部分中,我讨论了在手征展开中,两个、三个和四个核子之间的力的构造已经部分地进行到五阶的新进展。它还表明,根据这些力量与相应的理论不确定性的估计,需要在几个核子系统的三核子力可以明确地建立。我还介绍了晶格制定这些部队,这使得真正的从头计算的原子核结构和反应。我提出了一些相关的结果的核晶格的方法。最后,我讨论了如何少核子系统和原子核可以用来探索对称性和物理内外的标准模型。
英文摘要:
I review the chiral dynamics of nuclear physics. In the first part, I discuss the new developments in the construction of the forces between two, three and four nucleons which have been partly carried out to fifth order in the chiral expansion. It is also shown that based on these forces in conjunction with the estimation of the corresponding theoretical uncertainties, the need for three-nucleon forces in few nucleon systems can be unambiguously established. I also introduce the lattice formulation of these forces, which allow for truly ab initio calculations of nuclear structure and reactions. I present some pertinent results of the nuclear lattice approach. Finally, I discuss how few-nucleon systems and nuclei can be used to explore symmetries and physics within and beyond the Standard Model.
