Dipole models and parton saturation in ep scattering
L. Motyka, K. Golec-Biernat, G. Watt
In this contribution we briefly review the current status of the dipole models and parton saturation on the basis of results presented at the HERA-LHC workshops in the years 2006-2…
Parton Distributions and QCD at LHCb
R. S. Thorne, A. D. Martin, W. J. Stirling +1
We consider the impact that can be made on our understanding of parton distributions (PDFs) and QCD from early measurements at the LHCb experiment. The high rapidity values make th…
Exclusive Diffractive Processes within the Dipole Picture
G. Watt
We discuss two different models for the impact parameter dependent dipole cross section: one based on DGLAP evolution and the other inspired by the Balitsky-Kovchegov equation. The…
Recent Progress in Global PDF Analysis
G. Watt, A. D. Martin, W. J. Stirling +1
We discuss selected topics in the forthcoming MSTW 2008 determination of parton distributions by global analysis. The tolerance parameter controlling the uncertainties on the parto…
Exclusive photoproduction at the Tevatron and LHC within the dipole picture
L. Motyka, G. Watt
We provide predictions for the rapidity distributions of exclusive photoproduced J/psi and Upsilon mesons, and Z^0 bosons, at the Tevatron and LHC. We use the equivalent-photon app…
Impact parameter dependent colour glass condensate dipole model
G. Watt, H. Kowalski
We show that the colour glass condensate dipole model of Iancu, Itakura and Munier, improved to include the impact parameter dependence, gives a good fit to the total gamma* p cros…
