论文摘要
我们调查了单一重型重子的质量如何发生核物质的变化。即使在同胞素对称性破裂的情况下，单一重型重子的质谱也成功地描述了，我们将研究扩展到了单个重型巴里子的介质修饰。由于所有动态参数是通过解释自由空间中SU（3）光（3）光（3）光（3）的质谱而确定的，因此我们可以直接实现动力学参数的密度依赖性功能，该功能已经通过重现SU（SU（3）光（3）光（3）光（3）核物质和介质修饰的动力学依赖性。我们预测并讨论单一重型重子的质量的密度依赖性。
We investigate how the masses of singly heavy baryons undergo changes in nuclear matter. The mass spectrum of the singly heavy baryons was successfully described in a pion-mean field approach even with isospin symmetry breaking, based on which we extend the investigation to the medium modification of the singly heavy baryons. Since all dynamical parameters were determined by explaining the mass spectrum of the SU(3) light and singly heavy baryons in free space, we can directly implement the density-dependent functionals for the dynamical parameters, of which the density dependence was already fixed by reproducing the bulk properties of nuclear matter and medium modification of the SU(3) light baryons. We predict and discuss the density dependence of the masses of the singly heavy baryons.
