The product branching fraction of Ds+?f0(980)e+?e,f0(980)??0?0 is measured to be (7.9±1.4stat±0.4syst)×10-4, with a statistical significance of 7.8?. Furthermore, the upper limits on the product branching fractions of Ds+?f0(500)e+?e with f0(500)??0?0 and the branching fraction of Ds+?KS0KS0e+?e are set to be 7.3×10-4 and 3.8×10-4 at 90% confidence level, respectively. Our results provide valuable inputs to the understanding of the structures of light scalar mesons. © 2022 authors.
