(2022). Study of the decay ds+ → KS0 KS0 π+ and observation of an isovector partner to f0 (1710). Physical Review D, 105(5) doi:10.1103/PhysRevD.105.L0511032470-0010https://doi.org/10.1103/PhysRevD.105.L051103https://hdl.handle.net/20.500.12713/2775Using 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+?KS0KS0?+ 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-?+ in an earlier work, implying the existence of an isospin one partner of the f0(1710). The branching fraction of the decay Ds+?KS0KS0?+ is determined to be B(Ds+?KS0KS0?+)=(0.68±0.04stat±0.01syst)%. © 2022 authors.
