We demonstrate the different effect of different baryons impurities on the static properties of nuclei within the framework of the relativistic mean-field model. Systematic calculations show that $\Lambda_c^+$ and $\Lambda_b$ has the gluelike role the same as $\Lambda$ hyperon for lighter hypernuclei. $\Xi^-$ and $\Xi_c^0$ hyperon has the gluelike role only for the protons distribution in nuclei, and for the neutrons distribution $\Xi^-$ and $\Xi^0_c$ hyperon plays a repulsive role. On the other hand, $\Xi^0$ and $\Xi^+_c$ hyperon attracts surrounding neutrons and reveals a repulsive force to the protons. We find the different effect of different baryons impurities on the nuclear core is due to their different isospin, and $\rho$ mesons play an important role.
Keywords:hypernuclei
