First amplitude analysis of ψ(3686)→γKS0KS0 with a one-channel K-matrix finds four f0 and three f2 poles consistent with known states and reports branching-fraction ratios to J/ψ decays that constrain possible glueball content.

Amplitude analysis of $\psi(3686)\to \gamma K_S^0 K_S^0 $
First amplitude analysis of ψ(3686)→γKS0KS0 with a one-channel K-matrix finds four f0 and three f2 poles consistent with known states and reports branching-fraction ratios to J/ψ decays that constrain possible glueball content.
