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.

abstract
We calculate glueball and torelon masses as well as the lowest lying hybrid potential in addition to the static ground state potential in lattice simulations of QCD with two flavours of dynamical Wilson fermions. The results are obtained on lattices with $16^3\times 32$ and $24^3\times 40$ sites at $\beta=5.6$, corresponding to a lattice spacing, $a^{-1}=2.65^{+5}_{-8}$ GeV, as determined from the Sommer force radius, at physical sea quark mass. The range spanned in the present study of five different quark masses is reflected in the ratios, $0.83\geq m_{\pi}/m_{\rho}\geq 0.57$.

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.
