Parton distribution function for the gluon condensate
Yoshitaka Hatta, Yong Zhao
Abstract
Motivated by the desire to understand the nucleon mass structure in terms of light-cone distributions, we introduce the twist-four parton distribution function $F(x)$ whose first moment is the gluon condensate in the nucleon. We present the equation of motion relations for $F(x)$ and discuss the possible existence of the delta function (``zero mode'') contribution at $x=0$. We also perform one-loop calculations for quark and gluon targets.
