The effect of different baryons impurities
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 $Λ_c^+$ and $Λ_b$ has the same attracting role as $Λ$ hyperon does in lighter hypernuclei. $Ξ^-$ and $Ξ_c^0$ hyperon has the attracting role only for the protons distribution, and has a repulsive role for the neutrons distribution. On the contrary, $Ξ^0$ and $Ξ^+_c$ hyperon attracts surrounding neutrons and reveals a repulsive force to the protons. We find that the different effect of different baryons impurities on the nuclear core is due to the different third component of their isospin.
