At
present the theoretical frontier has reached the level when for
certain, mostly inclusive
processes, we can perform all order perturbative QCD
resummations. The results are
usually expressed as evolution equations, which govern the
variation of scattering amplitude as the energy of the process
increases. These evolution
equations in QCD aim to replace the old Reggeon
calculus, broadly used for high
energy hadron phenomenology.
On
theoretical side I am looking for an effective field theoretical
description of high energy
phenomena, which are traditionally discussed in terms of
the Regge phenomenology. The
ultimate goal is to derive and solve an effective Reggeon
Field Theory (RFT) as the correct
limit of QCD at high energies. The derivation is based on leading order perturbative
resummation and includes various
non-linear effects induces by
high gluon densities of colliding particles.
Apart of purely theoretical interest in
understanding the high energy
limit of QCD, the RFT should be an important tool for collider phenomenology . These are deep inelastic scattering experiments at HERA
and eRHIC, as well
as hadron and heavy ion collisions at the LHC, RHIC and TeVatron. One of the central questions to be studied is the
effect of high energy
resummation on proton structure functions. The latter are broadly used for computing
scattering processes at hadron
colliders. Precise knowledge of proton structure
functions is crucial for many experiments, and especially for the success of the research program at
the
LHC.
