Heavy Baryons as Skyrmion with $1/m_Q$ Corrections

Abstract

We take into account the $1/m_Q$ corrections upto $1/N_c$ order in the heavy-meson-soliton bound state approach for heavy baryons. With these corrections, the mass spectra of baryons with $c$-quark as well as of those with $b$-quark are well reproduced. For charmed baryons, however, the correction to the mass spectra amounts to about 300 MeV, which is not small compared to the leading order binding energy, $\sim 800$ MeV.
