高密核物质中核子的运动对于K介子的等效质量和能量的影响
Influence of nucleon motion on the effective mass and energy of kaon in dense nuclear matter
摘要
Abstract
In the present paper, the effective mass and energy of kaon in dense and hot nuclear matter is studied. Our special attention is paid to the comparison of various definitions of quasi-particle model of kaons used in transport theories. The effective mass of kaon defined in popular mean field theory increases with increasing of the density of nuclear matter, while the quantity used in covariant kaon dynamics decreases with the density increasing. The properties of mean field acting on kaon by hot and dense nuclear matter depends not only on the form of quasiparticle model of kaons, but on the motion of nucleons around it.关键词
