We present recent work on the determination of several scalar and tensor resonances produced in $J/\psi$ radiative decays. We extract 7 total inelastic resonances, of which the most interesting ones are the $f_0(1500)$ and $f_0(1710)$, considered glueball candidates. We implement many different parameterizations fulfilling the unitarity and analyticity requirements to asses our uncertainties. Fina

Due to the high production of light mesons J/ψ radiative and hadronic decays, the largest sample of J/ψ events accumulated at the BESIII detector offers a unique laboratory to study the light mesons spectroscopy and search for the light exotic states. In this talk, we shall report the recent progresses on the light meson spectroscopy achieved at BESIII.

The graviton soft wall model (GSW) provides a unified description of the scalar
glueball and meson spectra with a unique energy scale. We use this model to calculate the masses of the odd and even ground states of glueballs for various spins. In addition, the spectra of the $\rho$, $a_1$,$\eta$ and $\pi$ mesons will be addressed. Results are in excellent agreement with current experimental dat

A coupled-channel analysis of the BES3 data on the J/Psi radiative decay has been performed to identify the spectrum of scalar and of tensor mesons.The fit includes the BES3 data,the data from antiproton-nucleon annihilation and the data on pipi scattering. The analysis reveals the existence of ten scalar isoscalar resonances. In the tensor sector the radiative J/Psi data show only evidence for f2

A coupled-channel analysis of data on radiative $J/\psi$ decays constrained by
further data reveals the existence of ten scalar isoscalar resonances. Five seem to be mainly SU(3) singlet, five mainly octet states. Pure octet mesons should not be produced in radiative $J/\psi$ decays. But their yield is significant and peaks at 1865 MeV with no background. Singlet mesons are produced over a wide
