有效NN相互作用的低尺度饱和及其对称性

Low scale saturation of Effective NN Interactions and their Symmetries

E. Ruiz Arriola

摘要:

Skyrme力参数可以通过在特征动量尺度下粗粒化NN相互作用来唯一地确定。我们展示了如何精确Vlowk势二阶动量准确和普遍饱和的物理NN散射阈值参数在CM动量尺度约为λ =250兆电子伏的S波和λ =100兆电子伏的P波。先前揭示的维格纳和塞伯对称性模式在这些尺度上也是饱和的。

英文摘要:

The Skyrme force parameters can be uniquely determined by coarse graining the NN interactions at a characteristic momentum scale. We show how exact Vlowk potentials to second order in momenta are accurately and universally saturated with physical NN scattering threshold parameters at CM momentum scales of about Lambda=250 MeV for the S-waves and Lambda=100 MeV for the P-waves. The pattern of Wigner and Serber symmetries unveiled previously is also saturated at these scales.
