The effect of different baryons impurities

Abstract

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 same attracting role as $\Lambda$ hyperon does in lighter hypernuclei. ${\Xi }^{-}$ and ${\Xi }_c^0$ hyperon has the attracting role only for the protons distribution, and has a repulsive role for the neutrons distribution. On the contrary, ${\Xi }^0$ and ${\Xi }_c^{+}$ 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.
