Description
Experiments show that the flavor-singlet pseudoscalars usually have large production ratios in the radiative decays of $J/\psi$.
In this work we perform the first lattice investigation on this topic based on a gauge ensemble generated on an anisotropic lattice with two degenerate light dynamical quarks. The mass parameter of the light quarks is tuned to give a pion mass around 300 MeV. The annihilation diagrams of light quarks are calculated using the distillation method.
