Self-consistently recomputing the pion mean fields with N_c-1 valence quarks improves the chiral quark-soliton model predictions for singly heavy baryon masses and shows no soliton solution exists for doubly heavy baryons.
(A5) The free parameters Λ1, Λ2, and c are determined by reproducing the pion decay constant fπ = 93 MeV and the pion mass mπ = 139 MeV in the mesonic sector

Improved pion mean fields and masses of singly heavy baryons
Self-consistently recomputing the pion mean fields with N_c-1 valence quarks improves the chiral quark-soliton model predictions for singly heavy baryon masses and shows no soliton solution exists for doubly heavy baryons.
