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 Expansion (OPE) ambiguities. Recent work on infrared freezing of Euclidean observables is also di...
متن کاملOverview of Perturbative Qcd †
I review theoretical techniques and current issues in perturbative QCD, primarily as applied to jet physics at colliders. † Presented at the XXXI st Rencontres de Moriond, March 23–30, 1996, Les Arcs, France
متن کاملBasics of Qcd Perturbation Theory
This is an introduction to the use of QCD perturbation theory, emphasizing generic features of the theory that enable one to separate short-time and long-time e ects. I also cover some important classes of applications: electron-positron annihilation to hadrons, deeply inelastic scattering, and hard processes in hadron-hadron collisions.

متن کاملProgress in Perturbative Qcd
We briefly summarize some recent theoretical developments in perturbative QCD, emphasizing new ideas which have led to widening the domain of applicability of perturbation theory. In particular, it is now possible to calculate efficiently processes with many partons; the high order behavior of perturbation theory can be at least partly understood by going beyond leading twist accuracy; factoriz...
متن کاملDevelopments in Perturbative Qcd
A brief review of key recent developments and ongoing projects in perturbative QCD theory, with emphasis on conceptual advances that have the potential for impact on LHC studies. Topics covered include: twistors and new recursive calculational techniques; automation of one-loop predictions; developments concerning NNLO calculations; the status of Monte Carlo event generators and progress in mat...
