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.

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.File in questo prodotto:
