Reggeon interactions in perturbative QCD
, 1994
"... We study the pairwise interaction of reggeized gluons and quarks in the Regge limit of perturbative QCD. The interactions are represented as integral kernels in the transverse momentum space and as operators in the impact parameter space. We observe conformal symmetry and holomorphic factorization i ..."

Multiparticle production and perturbative QCD
, 2001
"... The perturbative quantum chromodynamics (QCD) is quite successful in the description of main features of multiparticle production processes. Ten most appealing characteristics are described in this brief review talk and compared with QCD predictions. The general perturbative QCD approach is demonstr ..."

Perturbative QCD Applied to Baryons
, 1998
"... We review standard applications of perturbative QCD to baryon production, and argue by examining data that it is generally relevant at high but experimentally feasible momentum transfers. Then we consider some new initiatives, particularly meson photoproduction off baryons and the seeming quagmire o ..."

RECENT DEVELOPMENTS IN PERTURBATIVE QCD ∗
, 2006
"... A brief overview of some recently active topics in perturbative QCD, including: string-inspired recursion techniques at tree level; recursion approaches and automation of standard techniques for 1-loop calculations; the status of NNLO jet calculations; and non-trivial structures that appear in highe ..."

The Perturbative QCD Potential and the
"... We include the full second-order corrections to the static QCD potential in the analysis of the t t threshold cross section. There is an unexpectedly large difference between the QCD potential improved by the renormalization-group equation in momentum space and the potential improved by the reno ..."

by the renormalization-group equation in coordinate space. This difference remains even at a fairly short distance 1=r ' 100 GeV and its origin can be understood within perturbative QCD. We scrutinize the theoretical uncertainties of the QCD potential in relation to the t t threshold cross section
SECONDARY REGGEONS IN PERTURBATIVE QCD
, 2002
"... Using the Kirschner-Lipatov equation as a basis, we study high energy elastic quark-quark amplitudes, which correspond to secondary Reggeons and pion exchange in the double-logarithmic approximation of perturbative QCD. 1. The high energy behaviour of elastic scattering amplitudes is described usual ..."

Perturbative and non-perturbative QCD
"... In these lectures we give a concise introduction to the ideas of renormalon calculus in QED and QCD. We focus in particular on the example of the Adler D function of vacuum polarization, and on relations between perturbative renormalon ambiguities and corresponding non-perturbative Operator Product ..."
