| Publication Abstract: | We present results for the $gg$-part of the one-loop corrections to the recently introduced ``topological charge'' PDF $\widetilde F(x)$. In particular, we give expression for its evolution kernel. To enforce strict compliance with the gauge invariance requirements, we have used on-shell states for external gluons, and have obtained identical results both in Feynman and light-cone gauges. No ``zero mode'' $\delta (x)$ terms were found for the twist-4 gluon PDF $\widetilde F(x)$ |
