Abstract

The Born cross sections and effective form factors for process e+e−→Ξ−¯Ξ+ are measured at eight center-of-mass energies between 2.644 and 3.080 GeV, using a total integrated luminosity of 363.9 pb−1 e+e− collision data collected with the BESIII detector at BEPCII. After performing a fit to the Born cross section of e+e−→Ξ−¯Ξ+, no significant threshold effect is observed.
