Conformal bootstrap for the BFKL pomeron
"... We calculate the interaction vertex of three BFKL states including the bare triple BFKL Pomeron coupling and discuss its relation with the correlation functions in twodimensional conformal field theory. We construct the operator algebra of the fields interpolating the BFKL states and show that in t ..."

that in the multicolor limit the vertex satisfies the constraints imposed by the conformal bootstrap on the structure constants of the operator product expansion in conformal field theory. Recent studies of the highenergy scattering of heavy onium states within the BFKL approach indicate an intrinsic relation

"... I discuss radiative corrections to the BFKL equation for high energy cross sections in perturbative QCD. Due to the gluon Reggeization in the nexttoleading ln s approximation, the form of the BFKL equation remains unchanged and the corrections to the BFKL kernel are expressed in terms of the twol ..."

The BFKL Pomeron Calculus: Probabilistic Interpretation and High Energy Amplitude.
, 2006
"... Abstract: In this paper we continue to pursue a goal of finding the effective theory for high energy interaction in QCD based on the colour dipole approach, for which the BFKL Pomeron Calculus gives a low energy limit. The two key problems, that we consider are the following: the probabilistic inter ..."

interpretation of the BFKL Pomeron Calculus and the possible scenario for the asymptotic behaviour of the scattering amplitude at high energy in QCD. In this paper we show that the generating functional approach is equivalent to the BFKL Pomeron Calculus and leads to a clear interpretation of this calculus
BFKL Monte Carlo for Dijet Production at Hadron Colliders ∗
, 2000
"... The production of jet pairs at large rapidity difference at hadron colliders is potentially sensitive to BFKL physics. We present the results of a BFKL Monte Carlo calculation of dijets at the Tevatron. The Monte Carlo incorporates kinematic effects that are absent in analytic BFKL calculations; the ..."

to describe many highenergy processes. The BalitskyFadinKuraevLipatov (BFKL) equation [ 1] performs such a resummation for virtual and real soft gluon emissions in such processes as dijet production at large rapidity difference in hadronhadron collisions. BFKL resummation gives [ 2] a subprocess cross
The Collision Energy Dependence of Dijet Cross Sections as a Probe of BFKL Physics
, 1998
"... The dependence of the subprocess cross section for dijet production at fixed transverse momentum on the (large) rapidity separation ∆y of the dijets can be used to test for ‘BFKL physics’, i.e. the presence of higher–order (αs log ∆y) n contributions. Unfortunately in practice these subtle effects a ..."

We propose a simple ratio test using two different collider energies in which the parton distribution dependence largely cancels. Such a ratio does distinguish between the ‘asymptotic ’ analytic BFKL and lowestorder QCD

"... After a brief review of the BFKL approach to Regge processes in QCD and in supersymmetric (SUSY) gauge theories we propose a strategy for calculating the nexttonexttoleading order corrections to the BFKL kernel. They can be obtained in terms of various crosssections for Reggeized gluon interacti ..."
