Hadron resonances as rovibrational states

A rovibrational model, including anharmonic, centrifugal, and Coriolis corrections, is used to calculate π, K, N, and ? orbital and radial resonances. The four orbital excitations of the π meson correspond to the b(1235), π₂(1670), b₃(2030), and π₄(2250) resonances. Its first four radial excitations correspond to the π(1300), π(1800), π(2070), and π(2360) resonances. The orbital excitations of the K meson are interpreted as the K₁(1270), K₂(1770), K₃(2320), and K₄(2500) resonances; its radial excitations correspond to the K(1460) and K(1830) resonances. The N orbital excitations are identified with the N(1520), N(1680), N(2190), N(2220), and N(2600) resonances. The first four radial excitations of the N family correspond to the N(1440), N(1880), N(2100), and N(2300) resonances. The orbital excitations of the ? baryon are associated with the ?(1670), ?(1915), ?(2100), and ?(2250) resonances, whereas its radial excitations are identified with the ?(1660), ?(1770), and ?(1880) resonances. The proposed rovibrational model calculations show a good agreement with the corresponding experimental values and allow for the prediction of hadron resonances, thereby proving to be useful for the interpretation of excited hadron spectra.
