Mass of Pseudoscalar Gluonium: A Higher-Loop QCD Sum-Rule Estimate

Abstract

Higher-loop corrections to the pseudoscalar ( $0^{-+}$ ) gluonium correlation function will be used to obtain the leading gluon condensate contributions to the subtraction-independent QCD sum-rules. The effect of these higher-loop corrections on the sum-rule estimates of the pseudoscalar gluonium mass will be investigated. The final results of this analysis compare favourably with $S U (3)$ lattice simulations.
