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

High Energy Physics - Phenomenology 2021-07-01 v2

Abstract

Higher-loop corrections to the pseudoscalar (0+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 SU(3)SU(3) lattice simulations.
