| 英文摘要 | We investigate the process e(+)e(-) -> k (k) over barj/psi at center-of-mass energies from 4.189 to 4.600 gev using 4.7 fb(-1) of data collected by the besiii detector at the bepcii collider. the born cross sections for the reactions e(+)e(-) -> k(+)k(-)j/psi and k(s)(0)k(s)(0)j/psi are measured as a function of center-of-mass energy. the energy dependence of the cross section for e(+)e(-) -> k(+)k(-)j/psi is shown to differ from that for pi(+)pi(-)j/psi in the region around the y(4260). in addition, there is evidence for a structure around 4.5 gev in the e(+)e(-) -> k(+)k(-)j/psi cross section that is not present in pi(+)pi(-)j/psi. |
