摘要X(1835) has been treated as a baryonium with sizable gluon content, and to be almost flavor singlet. This picture allows us to rationally understand X(1835)production in J/psi radiative decays, and its large couplings with p (p) over bar, eta'pi pi. The processes Y(1S) --> gamma X (1835) and J/psi --> omega (1835) have been examined. It has been found that Br(Y(1S) --> gamma X(1835))Br(X(1835) --> p (p) over bar)<6.45 x 10(-7), which is compatible with CLEO's recent experimental result (Phys. Rev. D 73, 032001 (2006) hep-ex/0510015). The branching fractions Br (J/psi --> omega X (1835)), Br (J/psi --> rho X (1835)) with X (1835) --> p (p) over bar and X (1835) --> eta'pi(+)pi(-) have been estimated by the quark-pair creation model. We show that they are heavily suppressed, so the signal of X(1835) is very difficult, if not impossible, to be observed in these processes. The experimental checks for these estimations are expected. The existence of the baryonium nonet is conjectured, and a model-independent derivation of their production branching fractions is presented.
