Resummation for QCD Hard Scattering
We resum distributions that are singular at partonic threshold (the elastic limit) in heavy quark production, in terms of logarithmic behavior in moment space. The method may be applied to a variety of cross sections sensitive to the edge of phase space, including transverse momentum distributions. Beyond leading logarithm, dependence on the moment variable is controlled by a matrix renormaliza...
متن کاملThreshold Resummation for QCD Hard Scattering
We describe the resummation of singular distributions at partonic threshold in heavy quark production, generalizing results for Drell-Yan and other electroweak hard-scattering processes.
متن کاملOn the Resummation of Singular Distributions in QCD Hard Scattering
We discuss the resummation of distributions that are singular at the elastic limit of partonic phase space (partonic threshold) in QCD hard-scattering cross sections, such as heavy quark production. We show how nonleading soft logarithms exponentiate in a manner that depends on the color structure within the underlying hard scattering. This result generalizes the resummation of threshold singul...
متن کاملResummation in Hard QCD Processes
We show that the resummation of large radiative corrections in QCD processes can be performed both in covariant gauge and in axial gauge. We extend the resummation technique to inclusive processes, concentrating on deeply inelastic scattering, Drell-Yan production, and inclusive heavy meson decays in end-point regions. Leading and next-to-leading logarithms produced by radiative corrections are...
متن کاملHard Scattering in Qcd
Recent developments in the theory and experiment of QCD hard scattering are described. 1 Preamble: How Perturbative QCD Works This has been an active year for experimental results and theoretical developments in quantum chromodynamics. In this talk I will cover a selection of topics presented at this conference, tied together by the interplay of soft and hard physics. QCD is certainly the most ...
