Abstract

Using 6.32 fb-1 of e+e- collision data recorded by the BESIII detector at center-of-mass energies between 4.178 to 4.226 GeV, we present the first measurement of the decay Ds+→f0(980)e+νe,f0(980)→π0π0. The product branching fraction of Ds+→f0(980)e+νe,f0(980)→π0π0 is measured to be (7.9±1.4stat±0.4syst)×10-4, with a statistical significance of 7.8σ. Furthermore, the upper limits on the product branching fractions of Ds+→f0(500)e+νe with f0(500)→π0π0 and the branching fraction of Ds+→KS0KS0e+νe 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.
