We investigate the changes in masses of singly heavy baryons in nuclear matter and find that they are highly sensitive to the modifications of heavy meson mass.
We investigate how the masses of 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 singly heavy baryons in nuclear matter. We generalize the vector-meson Lagrangian including the heavy-meson soliton interaction. The mass spectrum of singly heavy baryons 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 in a nuclear medium is rather sensitive to the medium modifications of the heavy meson mass.
