It is predicted that the Lorentz-scalar effective mass of $\\Sigma_b$ becomes smaller than that of $\\Xi_b$ at moderate nuclear matter density, and as the density increases, namely, $m^*_{\\Sigma_b} < m^*_{\\Xi_b}$, although in vacuum $m_{\\Sigma_b} > m_{\\Xi_b}$. We also study the effects of the repulsive Lorentz-vector potentials on the excitation energies of these bottom baryons.","authors_text":"K.
