Abstract

We show that it is possible to improve the infrared aspects of the standard treatment of the DGLAP‐CS evolution theory to take into account a large class of higher‐order corrections that significantly improve the precision of the theory for any given level of fixed‐order calculation of its respective kernels. We illustrate the size of the effects we resum using the moments of the parton distributions.
