Abstract: By exploiting in large-N YM the change of variables from the gauge connection to the ASD part of its curvature by a non-SUSY version of the Nicolai map, we show that certain twistor Wilson l...

Topological Charge Screening Pseudoscalar Glueballs
2010/10/25
Topological charge screening in the QCD vacuum is found to provide crucial nonperturbative contributions to the short-distance expansion of the pseudoscalar (0¡+) glueball correlator. The screen...
