Abstract
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 Q being b or c 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].
