Probing the High Energy
Limit of QCD
The high energy limit of
scattering processes in QCD is, at least on the purely theoretical level,
described by the BFKL equation. The BFKL dynamics can be used for the
prediction of many multi-jet processes relevant for 'background studies' at the
LHC. At the same time, the study of these QCD events will probe our
understanding of QCD (and field theory in general) in a region less well
understood than the super-perturbative region with one very hard
scale.
However, most
phenomenological studies of BFKL fail miserably when confronted with data. In
this talk I will critically review the application of leading log (LL) BFKL in
application of LL eigen functions in the study
of the NLL BFKL kernel. We then introduce a recently proposed iterative
solution of the NLL BFKL equation that allows detailed study of physical
properties of the BFKL evolution.
