选择微观状态方程

Selecting microscopic Equations of State

G. Taranto, M. Baldo, G. F. Burgio

摘要:

我们比较了微观多体方法中导出的一组状态方程,并研究了它们对重离子碰撞核的唯象数据和中子星的天体物理观测的预测。我们发现,所有的数据,放在一起,把强约束不容易被准确地履行。然而,没有发现重大的差异之间的状态方程和相对于数据。结果提供了一个估计的不确定性的理论预测在微观水平上的核物质状态方程。

英文摘要:

We compare a set of equations of state derived within microscopic many-body approaches, and study their predictions as far as phenomenological data on nuclei from heavy ion collisions, and astrophysical observations on neutron stars are concerned. We find that all the data, taken together, put strong constraints not easy to be fulfilled accurately. However, no major discrepancies are found among the selected equations of state and with respect to the data. The results provide an estimate of the uncertainty on the theoretical prediction at a microscopic level of the nuclear equation of state.
