A Discussion on the Problems in the Study of the Density Dependence of the SymmetryEnergy with Transport Models

  • 摘要: 本文非常简要地介绍了目前通过重离子碰撞中的对称能敏感观测量获取对称能密度依赖的研究现状,讨论了在输运理论模型计算中可能引起计算结果的不确定性的几个问题。特别与目前广泛采用的输运理论模型计算相关的3 个方面的问题,即对称势动量依赖项和中子、质子有效质量劈裂;不同电荷态Δ产生的阈能和相关截面的介质修正;输运理论模型中的多体关联和涨落等的处理等问题。
    This article briefly discusses the deviations appeared in the constraints on the density dependence of the symmetry energy obtained from the sensitive observables in the heavy ion collisions. The problems which possibly influence the constraints obtained from the comparison between the transport model calculations and experimental measurement of isospin sensitive observables are discussed. The three problems: (1) The momentum dependent part of symmetry potential and the neutron, proton effective mass splitting, (2) The isospin dependence of the medium correction of the thresholds and cross sections for different charged Δ production, (3) Many-body correlation and fluctuation treatment in transport model and other things in the transport model codes are discussed in more detail for the reference of the colleagues with common interest in nuclear community.
