| 英文摘要 | The decay j/psi -> gamma gamma phi is studied using a sample of 1.31 x 10(9) j/psi events collected with the besiii detector. two structures around 1475 mev/c(2) and 1835 mev/c(2) are observed in the gamma phi invariant mass spectrum for the first time. with a fit on the gamma phi invariant mass, which takes into account the interference between the two structures, and a simple analysis of the angular distribution, the structure around 1475 mev/c(2) is found to favor an assignment as the eta(1475) and the mass and width for the structure around 1835 mev/c(2) are consistent with the x(1835). the statistical significances of the two structures are 13.5 sigma and 6.3 sigma, respectively. the results indicate that both eta(1475) and x(1835) contain a sizeable s (s) over bar component. |
