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.
