Saturation and linear transport equation (2009)
We show that the GBW saturation model provides an exact solution to the one dimensional linear transport equation. We also show that it is motivated by the BK equation considered in the saturated...
Saturation effects in final states due to CCFM with absorptive boundary (2008)
Kutak, Krzysztof, Jung, Hannes
We apply the absorptive boundary prescription to include saturation effects in CCFM evolution equation. We are in particular interested in saturation effects in exclusive processes which can be...
What HERA may provide ? (2008)
Jung, Hannes, De Roeck, Albert, Bartels, Jochen, Behnke, Olaf, Blumlein, Johannes, Brodsky, Stanley, ...
More than 100 people participated in a discussion session at the DIS08 workshop on the topic What HERA may provide. A summary of the discussion with a structured outlook and list of desirable...
Valence quarks and $k_T$ factorisation (2008)
Deák, Michal, Jung, Hannes, Kutak, Krzysztof
We study in the $k_T$ factorisation framework jet production at LHC energies. In particular we are interested in valence quark and gluon initiated jets. The calculation of the relevant hard matrix...
A momentum Space Analysis of the Triple Pomeron Vertex in pQCD (2007)
Bartels, Jochen, Kutak, Krzysztof
We study properties of the momentum space Triple Pomeron Vertex in perturbative QCD. Particular attention is given to the collinear limit where transverse momenta on one side of the vertex are much...
We study the properties of the Triple Pomeron Vertex in the perturbative QCD using the twist expansion method. Such analysis allows us to find the momenta configurations preferred by the vertex. When...

Screening effects in the ultrahigh energy neutrino interactions (2003)
Kutak, Krzysztof, Kwiecinski, Jan
We study possible saturation effects in the total cross-section describing interaction of ultrahigh energy neutrinos with nucleons. This analysis is performed within the two approaches, i.e. within...
