The Resummed Gluon Anomalous Dimension and Structure Functions at Small x
J. Blümlein, A. Vogt
Abstract
The impact of the resummed next-to-leading logarithmic small-x contributions to the anomalous dimension γgg is evaluated for the unpolarized parton densities and structure functions of the nucleon. These new terms diminish the gluon distribution and overcompensate the contribution caused by the resummed leading logarithmic small-x anomalous dimension and the quarkonic anomalous dimensions beyond next-to-leading order.
