Mass of Pseudoscalar Gluonium: A Higher-Loop QCD Sum-Rule Estimate
D. Asner, R. B. Mann, J. L. Murison, T. G. Steele
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 SU(3) lattice simulations.
