| 英文摘要 | The process e(+)e(-) -> eta' j/psi is observed for the first time with a statistical significance of 8.6 sigma at center-of-mass energy root s = 4.226 gev and 7.3 sigma at root s = 4.258 gev using data samples collected with the besiii detector. the born cross sections are measured to be (3.7 +/- 0.7 +/- 0.3) and (3.9 +/- 0.8 +/- 0.3) pb at root s = 4.226 and 4.258 gev, respectively, where the first errors are statistical and the second systematic. upper limits at the 90% confidence level of the born cross sections are also reported at other 12 energy points. |
