The Unpolarized Gluon Anomalous Dimension at Small x
J. Blümlein, V. Ravindran, W. L. van Neerven +1
We discuss the quantitative consequences of the resummation of the small-x contributions to the anomalous dimensions beyond next-to-leading order in alpha_s and up to next order in…

Relations among polarized and unpolarized splitting functions beyond leading order
J. Blümlein, V. Ravindran, W. L. van Neerven
The role of various symmetries in the evaluation of splitting functions and coefficient functions is discussed. The scale invariance in hard processes is known to be a guiding tool…
