Title

Extending the QCD perturbative domain to higher energies

Abstract

The small-x evolution of the gluon density is characterized by a large effective coupling, due to both rapidity phase space and to tunneling to the strong-coupling Pomeron regime. The RG-improved approach allows to resum large subleading terms of alternating sign and considerably extends the validity of perturbative calculations. After a brief review, new results for both the (DIS) resummed splitting function and the (double DIS) Green function are presented.
