Abstract

Using e + e − collision data collected with the BESIII detector corresponding to an integrated luminosity of 44.2 fb − 1 , we measure the Born cross sections for the process e + e − → Ξ ( 1530 ) 0 Ξ ¯ 0 + c . c . at 48 center-of-mass energies between 3.51 and 4.95 GeV. The potential signal from non- D D ¯ decays for ψ ( 3770 ) , i.e., ψ ( 3770 ) → Ξ ( 1530 ) 0 Ξ ¯ 0 + c . c ., is investigated by fitting the dressed cross section, no obvious signal is found. The upper limit of B ( ψ ( 3770 ) → Ξ ( 1530 ) 0 Ξ ¯ 0 ) at 90% confidence level is given.
