Firstly, we review the Moebius invariance present in the Regge limit of
perturbative QCD, and argue that the associated conformal spins are related to
azimuthal angle correlations in the hadro-production of dijets.
Secondly, we report on progress in the study of the connection between
unitarity corrections at small x and critical behaviour of gravitational collapse in
five dimensions.

We address the computation of the four-point function of R-currents in N=4 SYM in the
Regge limit as a tool to study such regime in a gauge invariant framework. The
R-current is a close analog of the EM current in QED and SQED, which couple a gauge
invariant state ('photon') to a YM system. Gauge invariance guarantee that the
amplitude is free from infrared divergences. We discuss some...

We investigate the derivation of reggeon transition vertices from Lipatov's gauge
invariant effective action for high energy processes in QCD. In particular we address
the question of longitudinal integrations in order to reduce the vertices into the
required purely transverse form. We present a momentum space derivation of the
BFKL-kernel and verify the vanishing of the 2 to 3 reggeon...
