| 英文摘要 | Stimulated by the new evidence of Y(4274) observed in the j/psi phi invariant mass spectrum, we first propose the charmonium-like state Y(4274) as the S-wave D(s)(D) over bar (s0)(2317) + h.c. molecular state with J(P) = 0(-), which is supported well by dynamics study of the system composed of the pseudoscalar and scalar charmed mesons. The S-wave D (D) over bar (0)(2400) + h.c. molecular charmonium appears as the molecular partner of Y(4274), which is in accord with the enhancement structure appearing at 4.2 GeV in the J/psi omega, invariant mass spectrum from B. decays. Our study shows that the enhancement structures, i.e., the newly observed Y(4274) and the previously announced Y(4140)/Y(3930) in the J/psi phi and J/psi omega invariant mass spectra, can be understood well under the uniform framework of the molecular charmonium, which can be tested by future experiments.
