- The Born cross sections and effective form factors for process e(+)e(-) -> Xi(-)(Xi) over bar (+) 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(-) -> Xi(-)(Xi) over bar (+), no significant threshold effect is observed.
