报告摘要:
The J/psi radiative decay is one of the best place to study light hadrons, among which glueballs and hybrids are important objects searched by experiments for a long time. The production rates in J/psi radiative decays are very crucial for different types of light hadrons to be identified in experiments. This talk will review the lattice QCD predictions of glueball production rates, and then present recent lattice QCD results on qqbar mesons and the qqg hyrbrid. The connection with BESIII results will also be discussed.
