  We investigate how the masses of the singly heavy baryons undergo changes in
nuclear matter, based on a medium-modified SU(3) chiral soliton model. Having
explained the bulk properties of nuclear matter, we discuss the masses of the
singly heavy baryons in nuclear matter. We generalize the vector-meson
Lagrangian including the heavy-meson soliton interaction. The mass spectrum of
the singly heavy baryon are obtained with the effects of explicit SU(3)
symmetry breaking considered as a perturbation. The results show that the mass
of the singly heavy baryon mass in nuclear medium is rather sensitive to the
medium modifications of the heavy meson mass.
