QCD Glueball Sum Rules Revisited
We discuss several key problems of conventional QCD glueball sum rules in the spin-0 channels and showhow they are overcome by nonperturbative Wilson coefficients. The nonperturbative contributions originatefrom direct instantons and, in the pseudoscalar channel, additionally from topological charge...
