Abstract
Recently the LHCb Collaboration have found four baryonic states called Ω b (6316), Ω b (6330), Ω b (6340), and Ω b (6350) in the invariant mass spectrum. Possible spin-parity assignments of these resonances in the Quark-Diquark Model as P-wave baryons are discussed. Parameters of the effective Hamiltonian are determined from the observed spectrum of -baryons and compared with the ones extracted from the mass spectrum of -baryons. Alternative interpretation, in which the three lowest-mass states have the spin-parities JP = 3/2−, 3/2−, 5/2−, predicts an -baryon with the mass M ≃ 6304 MeV which is not yet seen experimentally.
