Scalar and tensor resonances in $$J/\psi $$ radiative decays

Abstract We perform a systematic analysis of the $$J/\psi \rightarrow \gamma \pi ^0\pi ^0$$ J / ψ → γ π 0 and $$\rightarrow K_S^0 K_S^0$$ K S partial waves measured by BESIII. use large set amplitude parametrizations to reduce model bias. determine physical properties seven scalar tensor resonances in 1– $$2.5 \, {\mathrm {GeV}} $$ 2.5 GeV mass range. These include well known $$f_0(1500)$$ f ( 1500 ) $$f_0(1710)$$ 1710 , that are considered be primary glueball candidates. The hierarchy resonance couplings determined from this favors latter as one with largest component.
