核子-核子相互作用的一种新展开

A New Expansion for Nucleon-Nucleon Interactions

David B. Kaplan, Martin J. Savage, Mark B. Wise

摘要:

我们为描述核子-核子相互作用的有效场论引入一种新的定义良好的功率计数。由于大的NN散射长度,它不同于手征微扰理论的其他应用,并通过引入不寻常的减法方案和重整化群分析来促进。展开式中的子前导阶的计算可以解析地完成,并且我们给出了1 S 0和3S 1 - 3D 1通道的结果。

英文摘要:

We introduce a new and well defined power counting for the effective field theory describing nucleon-nucleon interactions. Because of the large NN scattering lengths it differs from other applications of chiral perturbation theory and is facilitated by introducing an unusual subtraction scheme and renormalization group analysis. Calculation to subleading order in the expansion can be done analytically, and we present the results for both the 1S0 and 3S1-3D1 channels.
