The mass spectrum of beauty hadrons (
and bbb baryons) is computed in a non-relativistic phenomenological potential model. The potential comprises of short-range Coulomb potential, a screened confinement potential, and O(1/m) corrections predicted from lattice and pNRQCD studies. Among the spin-dependent interactions, spin-spin interaction is considered non-perturbatively, whereas spin-orbit and tensor interactions are considered perturbatively. The Matrix-Numerov method is used to numerically solve the non-relativistic Schrodinger equation to evaluate the mass spectra. We interpret 
as D-wave bottomonium state and 
and 
as S-wave bottomonium states. The mass spectrum of bbb baryons are evaluated under the diquark-quark model. The excited masses are computed by considering various radial and orbital excitations of the diquark as well as the diquark-quark system.
