    Abstract:

    The impact of the recently evaluated ‘irreducible’ contributions to the resummed next-to-leading logarithmic small-x anomalous dimension γgg is evaluated for the unpolarized parton densities and structure functions of the nucleon. These new terms diminish the gluon distribution and are found to overcompensate the contributions caused by the resummed leading logarithmic small-x anomalous dimension and the quarkonic anomalous dimensions beyond next-to-leading order.
