Abstract

Using e+e-annihilation data corresponding to a total integrated luminosity of 6.32 fb-1 collected at center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysis of the decay Ds+→KS0KS0π+ for the first time. An enhancement is observed in the KS0KS0 mass spectrum near 1.7 GeV/c2, which was not seen in Ds+→K+K-π+ in an earlier work, implying the existence of an isospin one partner of the f0(1710). The branching fraction of the decay Ds+→KS0KS0π+ is determined to be B(Ds+→KS0KS0π+)=(0.68±0.04stat±0.01syst)%.
