Description
The forward Drell-Yan scattering is an excellent probe of the proton structure down to very small x. In this region effects of BFKL evolution are strong. We study in detail these effects in the Drell-Yan structure functions. At small x and moderate invariant masses of the Drell-Yan pair also effects of higher twist operators and multiple scattering are expected to turn on. We model them using the GBW saturation model.
