Query: Spectrum of heavy baryons in the quark model   Single- and double- heavy baryons are studied in the constituent quark model.
The model Hamiltonian is chosen as a standard one with two exceptions : (1) The
color-Coulomb term depend on quark masses, and (2) an antisymmetric $LS$ force
is introduced. Model parameters are fixed by the strange baryon spectra,
$\Lambda$ and $\Sigma$ baryons. The masses of the observed charmed and bottomed
baryons are, then, fairly well reproduced. Our focus is on the low-lying
negative-parity states, in which the heavy baryons show specific excitation
modes reflecting the mass differences of heavy and light quarks. By changing
quark masses from the SU(3) limit to the strange quark mass, further to the
charm and bottom quark masses, we demonstrate that the spectra change from the
SU(3) symmetry patterns to the heavy quark symmetry ones.
