从温度场论虚时格林函数方法出发.推导了有限温度单ρ介子交换势,得出ρ介子随温度升高而变轻,这与利用QCD标度性质得到的结果一致.还得出ρ介子与核子相互作用的耦合常数随温度变化的规律也和σ介子与核子的相似.

The influence of short-range correlations in nuclei was investigated with realistic nuclear force. The nucleon-nucleon interaction was renormalized with Vlowk technique and applied to the Green's function calculations. The Dyson equation was reformulated with algebraic diagrammatic constructions. We also analyzed the binding energy of 4He, calculated with chiral potential and CD-Bonn potential. The properties of Green's function with realistic nuclear forces are also discussed. 展开更多
