Abstract :
By using k-factorization, we derive resummation formulas for the non-abelian qq contributions to both heavy flavour production by gluon fusion, and to the next-to-leading BFKL kernel. By combining this result with previous ones by Fadin et al. on the virtual terms, we also compute in closed form the complete qq contribution to the gluon anomalous dimension in the Q0-scheme. We find that qq resummation effects are important for heavy flavour production, but are instead small in the anomalous dimension eigenvalues, because of a cancellation between abelian and non-abelian contributions.
