Sudakov logarithm resummation for vector boson production at hadron colliders §
نویسنده
چکیده
A complete description of W and Z boson production at highenergy colliders requires the resummation of large Sudakov logarithms which dominate the production at small transverse momentum. Currently there are two techniques for performing this resummation: impact parameter space and transverse momentum space. We argue that the latter can be formulated in a way which retains the advantages of the former, while at the same time allowing a smooth transition to finite order dominance at high transverse momentum.

Sudakov Logarithm Resummation in Transverse Momentum Space for Electroweak Boson Production at Hadron Colliders
A complete description of W and Z boson production at high-energy hadron colliders requires the resummation of large Sudakov double logarithms which dominate the transverse momentum (qT ) distribution at small qT . We compare different prescriptions for performing this resummation, in particular implicit impact parameter space resummation versus explicit transverse momentum space resummation. W...
متن کاملKinematical Correlations for Higgs Boson Plus High P_{T} Jet Production at Hadron Colliders.
We investigate the effect of QCD resummation to kinematical correlations in the Higgs boson plus high transverse momentum (P(T)) jet events produced at hadron colliders. We show that at the complete one-loop order, the Collins-Soper-Sterman resummation formalism can be applied to derive the Sudakov form factor. We compare the singular behavior of resummation calculation to fixed order predictio...
متن کاملSoft Gluon Resummation in Transverse Momentum Space for Electroweak Boson Production at Hadron Colliders
The distribution of W and Z bosons produced with small transverse momentum (pT) at hadron colliders receives important contributions from large logarithms arising from soft gluon emission. Although conventionally the all-orders resummation of these ‘Sudakov’ logarithms is performed in impact parameter (Fourier transform) space, pT-space resummation is also possible, and offers certain advantage...
متن کاملElectroweak Vector Boson Production in Joint Resummation
We study the application of the joint resummation to electroweak boson production at hadron colliders. The joint resummation formalism resums both threshold and transverse momentum corrections to the transverse momentum distribution at next-to-leading logarithmic accuracy. We obtain a good description of the transverse momentum distribution of Z bosons produced at the Tevatron collider.
متن کاملHigher-order QCD corrections to vector boson production at hadron colliders
We present two recent results on higher-order QCD corrections to the production of vector bosons in hadron collisions. We discuss the resummation of logarithmic-enhanced QCD corrections at small values of qT and the matching procedure to consistently combine resummation with the fixed-order perturbative result at intermediate and large qT . We study the perturbative uncertainty of the results a...
