| 英文摘要 | In this work we study the structures near 4.3 GeV in the J/psi phi invariant mass spectra in B meson decay process B+ -> J/psi phi K+ and two photon fusion process gamma gamma -> J/psi phi. The Y(4274) as a DsDs0 (2317) molecular is studied in the Bethe-Salpeter equation approach with quasipotential approximation. The absence of Y(4274) in gamma gamma -> J/psi phi channel can be well explained by the decay widths of Y(4274) decaying to gamma gamma and J/psi phi. The distribution of mass difference released by CMS Collaboration is reproduced by two resonances near 4.3 GeV, Y(4274) and X(4320). The different production mechanism suggests X(4320) observed in the B decay should be the missing 3(3) P-1 charmonium state chi(c1)'', and different from X(4350) observed in two photon fusion which can be assigned as chi(c2)''.
