摘要:

夸克-介子耦合(QMC)模型在核子的夸克结构动力学与核介质内产生的相对论平均场之间建立了自洽关系。该模型在计算有限核基态可观测量、预测致密核物质以及冷非吸积中子星性质方面已取得成功。本文聚焦于该模型对超重区(包含能量和形变)的最新预测。尽管使用了显著更少的模型参数,但随着模型的演化,结果持续改善,对结合能给出了更好的预测。

英文摘要:

The Quark-Meson Coupling (QMC) model establishes a self-consistent relationship between the quark structure dynamics of a nucleon and the relativistic mean fields that arise within the nuclear medium. The model has been successful in calculating the ground-state observables of finite nuclei and in predicting the properties of dense nuclear matter, as well as cold, nonaccreting neutron stars. This paper focuses on the latest predictions from the model for the superheavy region, encompassing energies and deformations. Despite utilizing significantly fewer model parameters, the results have consistently improved as the model evolved, yielding better predictions for binding energies.
