My work with Lev Lipatov will be reviewed shortly.
The use of methods of integrable systems for treating QCD amplitudes,
parton and BFKL kernels is discussed.
We suggest a renewed view on non-renormalizable interactions treated perturbatively
within a kinematically dependent renormalization procedure. It is based on the usual BPHZ R-operation which is equally applicable to any local QFT independently whether it is renormalizable or not. The key point is that the renormalization constant becomes the function of kinematical variables acting as an...
An Invited talk at Lev Lipatov Memorial session
E?ects of non-zero chemical potential in the holographic QCD.
Approach by by Brodsky-Fadin-Kim-Lipatov-Pivovarov (BFKLP) for next-to-leading approximation (NLA) of Balitsky-Fadin-Lipatov-Kuraev (BFKL) evolution with generalized Brodsky-Lepage-McKenzie resummation of QCD coupling constant effects is reviewed. Applications of NLA BFKL within BFKLP approach for gamma-gamma scattering and dijet productions with large rapidity separation in hadron collisions ...
I will discuss the properties of the discrete BFKL solution and show that HERA data indicate that a state usually considered as a ground state has to decouple. As a consequence, the real ground state should be close to the non-perturbative region i.e., in the saturation region. This finding, together with the known property of BFKL that it should be sensitive to symmetries beyond Standard...
Regge cuts in QCD amplitudes are discussed. The cuts with negative signature which appear in the next-to-next-to-leading logarithmic approximation greatly complicate the derivation of the BFKL equation. Their contributions in the two- and three-loop approximations are presented
The Balitsky-Fadin-Kuraev-Lipatov equation presents a bound state of two reggeized gluons and is already known to the leading order for four decades. Its subleading corrections at the next-to-leading (NLO) level are also known both in QCD and maximally supersymmetric theory (SUSY N=4) for more than two decades. Going beyond the NLO order presents in general a non-trivial task and still to be...
We propose a new formalism for particle production in high energy collisions which aims to unify the collinear factorization approach and DGLAP evolution equation with that of BFKL/gluon saturation physics.
I discuss the implications of a new proposed approach to determine a^HLO_μ and α_QED by using space-like kinematics
