Abstract:	摘要： The processes γγ → ωϕ, ϕϕ, and ωω are measured using an 870 fb(-1) data sample collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. Production of vector meson pairs is clearly observed and their cross sections are measured for masses that range from threshold to 4.0 GeV. In addition to signals from well established spin-zero and spin-two charmonium states, there are resonant structures below charmonium threshold, which have not been previously observed. We report a spin-parity analysis for the new structures and determine the products of the η(c), χ(c0), and χ(c2) two-photon decay widths and branching fractions to ωϕ, ϕϕ, and ωω. 其他題名： Phys Rev Lett 出版者： United States: American Physical Society (APS) 出版日期： 2012-06-08 出處： Physical Review Letters, 2012-06, Vol.108 (23), p.232001 資源來源： American Physical Society Journals 識別號： ISSN: 1079-7114 識別號： EISSN: 1079-7114 識別號： DOI: 10.1103/PhysRevLett.108.232001 識別號： PMID: 23003948
