Topological Charge Screening and Pseudoscalar Glueballs
Topological charge screening in the QCD vacuum is found to provide crucial nonperturbative contributions tothe short-distance expansion of the pseudoscalar (0¡+) glueball correlator. The screening contributions enterthe Wilson coefficients and are an indispensable complement to the direct instanton...
