用相对论HF理论研究核物质的性能

Properties of Nuclear Matter in a Relativistic Hartree-fock Theory

本文在重正化的相对论量子场理论框架中导出了包含介子和重子的无限系统的相对论ＨＦ方程。方程的导出是以一个图解近似和重子传播子的Ｄｙｓｏｎ方程为基础。结果得到了一组带有一个关于单粒子光谱自洽条件的耦合的，非线性的重子自能的积分方程。对模型参数重正代之后可以复制核物质的饱和特性。

In this paper, relativistic Hartree-Fock(HF) equations are derived for an infinite system of masons and baryons in the framework of a renormalizable relativistic quantum field theory. The derivation is based on a diagrammatic approach and Dyson's equation for the baryon propagator. The result is a set of coupled, nonlinear integral equations for the baryon self-energy with a self-consistency condition on the single-particle spectrum. After renormalizing model parameters to reproduce nuclear matter saturation properties, HF results at low to moderate densities are similar to those in the mean-field (Hartree) approximation.
