Applicability of Perturbative QCD to B →
We examine the applicability of perturbative QCD to B meson decays into D mesons. We find that the perturbative QCD formalism, which includes Sudakov effects at intermediate energy scales, is applicable to the semi-leptonic decay B → Dlν, when the D meson recoils fast. Following this conclusion, we analyze the two-body non-leptonic decays B → Dπ and B → DD s. By comparing our predictions with e...
متن کاملApplicability of Perturbative QCD to Pion Virtual Compton Scattering
We study explicitly the applicability of perturbative QCD (pQCD) to the pion virtual Compton scattering. It is found that there are central-region singularities introduced by the QCD running coupling constant, in addition to the end-point singularities generally existed in other exclusive processes such as the pion form factor. We introduce a simple technique to evaluate the contributions from ...
متن کاملPerturbative 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 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...
