The numerical results indicate that the p $ \bar{{p}}$ , $ \Sigma$ $ \bar{{\Sigma}}$ , $ \Xi$ $ \bar{{\Xi}}$ , p $ \bar{{N}}$ (1440) , $ \Sigma$ $ \bar{{\Sigma}}$ (1660) , $ \Xi$ $ \bar{{\Xi}}^{{\prime}}_{}$ bound states maybe exist, and the new resonances X(1835) and X(2370) can be tentatively identified as the p $ \bar{{p}}$ and p $ \bar{{N}}$ (1440) (or N(1400) $ \bar{{p}}$ bound states, respectively, with some gluon constituents, and the new resonance X(2120) may be a pseudoscalar glueball. On the other hand, the Regge trajectory favors identifying the X(1835) , X(2120) and X(2370) as the excited $ \eta^{{\prime}}_{}$ (958) mesons with the radial quantum numbers n = 3 , 4 and 5, respectively.
