The in-medium sum rules are employed to calculate the shifts in the mass and residue as well as the scalar and vector self-energies of the heavy [Formula: see text] and [Formula: see text] baryons, with being or quark. The maximum shift in mass due to nuclear matter belongs to the [Formula: see text] baryon and it is found to be [Formula: see text]. In the case of residue, it is obtained that the residue of [Formula: see text] baryon is maximally affected by the nuclear medium with the shift [Formula: see text]. The scalar and vector self-energies are found to be [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text].
利用介质求和规则计算重子（[公式：见正文]，其中夸克为或夸克）的质量和留数的位移以及标量和矢量自能。由于核物质导致的质量最大位移属于重子，其值为[公式：见正文]。在留数的情况下，发现重子的留数受核介质的影响最大，位移为[公式：见正文]。标量和矢量自能分别为[公式：见正文]、[公式：见正文]、[公式：见正文]、[公式：见正文]、[公式：见正文]、[公式：见正文]以及[公式：见正文]、[公式：见正文]、[公式：见正文]、[公式：见正文]、[公式：见正文]和[公式：见正文]。
