Description
We present a relativistic constituent-quark model extended to describe all known baryons on a uniform basis. The corresponding Poincaré-invariant mass operator relies on a linear confinement and a hyperfine interaction derived from Goldstone-boson exchange. The relativistic three-quark system is solved along modified Faddeev equations adapted to treat long-range interactions. While the spectroscopy of baryons with u, d, and s flavors has been discussed before, we here focus primarily on the spectra of charm and beauty baryons, which have recently become amenable to new measurements especially at LHCb. Beyond the ground states of Λ, Σ, Ξ, and Ω baryons, containing c and b flavors, we also predict their first few excitations, which are expected to be manifested by future experiments.
