有限核、核物质及以后的夸克-介子耦合(QMC)模型

Quark-Meson-Coupling (QMC) model for finite nuclei, nuclear matter and beyond

P. A. M. Guichon, J. R. Stone, A. W. Thomas

摘要:

夸克-介子耦合模型自洽地将强子内部夸克结构的动力学与核物质中产生的相对论平均场联系起来,为低能核物理中的许多悬而未决的问题提供了自然的解释,包括多体核力的起源及其饱和,强子物质的自旋-轨道相互作用和性质,密度范围很广,直到中子星的核心。在这里,我们集中在四个方面的模型(i)一个完整的全面调查的理论,包括最新的发展,(ii)广泛的应用模型的基态性质的有限核和超核,与讨论的相似性和差异之间的QMC和Skyrme能量密度泛函,(iii)冷中子星和暖中子星中强子物质的平衡条件和组成及其与相对论平均场论结果的比较,(iv)对强子结构在介质中变化的基本观点的检验。

英文摘要:

The Quark-Meson-Coupling model, which self-consistently relates the dynamics of the internal quark structure of a hadron to the relativistic mean fields arising in nuclear matter, provides a natural explanation to many open questions in low energy nuclear physics, including the origin of many-body nuclear forces and their saturation, the spin-orbit interaction and properties of hadronic matter at a wide range of densities up to those occurring in the cores of neutron stars. Here we focus on four aspects of the model (i) a full comprehensive survey of the theory, including the latest developments, (ii) extensive application of the model to ground state properties of finite nuclei and hypernuclei, with a discussion of similarities and differences between the QMC and Skyrme energy density functionals, (iii) equilibrium conditions and composition of hadronic matter in cold and warm neutron stars and their comparison with the outcome of relativistic mean-field theories and, (iv) tests of the fundamental idea that hadron structure changes in-medium.
