We consider the transverse momentum dependent (TMD) quark densities of the
proton which are very important ingredients for unpolarized Drell-Yan
lepton pair production in proton-proton collisions at the LHC energies. We
calculate the TMD sea quark density as a convolution of the
Catani-Ciafaloni-Fiorani-Marchesini-evolved gluon distribution and the TMD
gluon-to-quark splitting function....

In my talk I will present twist expansion of differential cross-sections of forward Drell-Yan (DY) process at high energies. The expansion of all invariant DY form-factors is performed assuming GBW saturation model, and the saturation scale plays the role of the hadronic scale of OPE. Results are given both for the differential cross-sections dependent on the Drell-Yan pair transverse momentum...

We present the calculation of the forward jet vertex associated to a rapidity gap (coupling of a hard pomeron to the jet) in the
BFKL formalism at next-to-leading order(NLO). We handle the real emission contributions making use of the Lipatov's effective action. This result is important since it allows, together with the NLO non-forward gluon Green function, to perform NLO studies of jet...

We show how the photon input parton distribution function (PDF) may be calculated with good accuracy, and used in an extended DGLAP global parton analysis in which the photon is treated as an additional point-like parton. The uncertainty of the input photon PDF is relatively small, since the major part of the distribution (which is produced by the coherent emission of the photon from a proton...
