The Effects of the Exchange Diagram in the Self-energy of Mesons on the Properties of High Density Nuclear Matter
摘要
Abstract
Based on the nonlinear mean field model,the contribution of the exchange diagram in the self-energy of mesons is introduced.This correction leads to the variation of the in-medi-um meson mass with respect to the nuclear matter density.It also modifies the in-medium nu-cleon masses and the properties of high density nuclear matter.The equation of state for high density nuclear matter is softer due to the contribution of the exchange diagram.关键词
