报告摘要：With appropriate interpolating currents the mass spectrum of 0- - oddball is obtained in the framework of QCD Sum Rules (QCDSR). We find there are two stable oddballs with masses of 3.81 ± 0.12 GeV and 4.33 ± 0.13 GeV, and analyze their possible production and decay modes in experiments. Noticing that these 0- - oddballs with exotic quantum number are attainable in BESIII, BELLEII, PANDA, Super-B and LHCb experiments, we believe the long search elusive glueball could be measured shortly.
