Nikolai Zotov (Moscow State University)14/09/2014, 15:30Progress in QCDWe 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....Go to contribution page

Mr Tomasz Stebel (Jagiellonian University)14/09/2014, 15:50Progress in QCDIn 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...Go to contribution page

Mr José Daniel Madrigal Martínez (IPhT CEA Saclay)14/09/2014, 16:10Progress in QCDWe 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...Go to contribution page

Prof. Alan Martin (IPPP, Durham)14/09/2014, 16:30Progress in QCDWe 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...Go to contribution page
