Abstract

Scalar \cite{scalar_paper} and tensor \cite{tensor_paper} glueballs created in J/ψJ/\psi radiative decays are studied in quenched lattice QCD. Using two anisotropic lattices to approach the continuum limit, we compute the relevant form factors responsible for the decay rates for J/ψγG0++J/\psi\rightarrow\gamma G_{0^{++}} and J/ψγG2++J/\psi\rightarrow\gamma G_{2^{++}}. Comparing with the existing experimental data, it is argued that f0(1710)f_0(1710) is a favorable candidate for scalar glueball. The decay rate for J/ψγG2++J/\psi\rightarrow\gamma G_{2^{++}} is found to be quite substantial. A comprehensive search in the tensor channel on BESIII is therefore suggested.
