Abstract
Scalar \cite{scalar_paper} and tensor \cite{tensor_paper} glueballs created in 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 and . Comparing with the existing experimental data, it is argued that is a favorable candidate for scalar glueball. The decay rate for is found to be quite substantial. A comprehensive search in the tensor channel on BESIII is therefore suggested.
