标题： Dimensional Power Counting in Nuclei

摘要： 这本入门读物重述了温伯格关于原子核的维数幂次计数方法。 讨论了量子色动力学（QCD）和手征对称性在构建有效拉氏量中的作用。 曼尼哈和乔治的双尺度假设与振幅中的幂次计数相结合，揭示了原子核动能和势能尺度、强相互作用耦合常数的大小、介子交换电流的规模以及$N$- 核子力的相对大小。 给出了许多例子并与传统的核模型进行了比较。 显示英文摘要

摘要： Weinberg's dimensional power counting for nuclei is reprised in this primer. The role of QCD and chiral symmetry in constructing effective Lagrangians is discussed. The two-scale hypothesis of Manohar and Georgi is combined with power counting in amplitudes to shed light on the scales of nuclear kinetic and potential energies, the size of strong-interaction coupling constants, the size of meson-exchange currents, and the relative sizes of $N$-nucleon forces. Numerous examples are worked out and compared to conventional nuclear models.
