Electroweak-boson hadroproduction at large transverse momentum: factorization, resummation, and NNLO corrections
نویسندگان
چکیده
We study the resummation of singular distributions for electroweakboson production at large transverse momentum in hadronic collisions. We describe the factorization properties of the cross section near partonic threshold and construct the resummed cross section at next-toleading logarithmic accuracy in moment space in terms of soft gluon anomalous dimensions. We present full analytical results for the expansion of the resummed cross section up to next-to-next-to-leading order. Our results can be applied to W , Z, and virtual γ production at hadron colliders.

Production of Large Transverse Momentum W Bosons at the Tevatron
We discuss the production of W bosons at large transverse momentum in pp̄ collisions at the Tevatron Run I and II. W boson hadroproduction is a process of relevance in testing the Standard Model and in estimates of backgrounds to new physics. The next–to–leading order cross section in the region of large transverse momentum is dominated by threshold soft– gluon corrections which arise from incom...
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 کاملNNLO Soft-gluon Corrections for the Z-boson and W-boson Transverse Momentum Distributions
We present results for the Z-boson and W -boson transverse momentum (pT ) distributions for large pT at LHC and Tevatron energies. We calculate complete next-to-leadingorder (NLO) QCD corrections as well as soft-gluon corrections at next-to-next-to-leadingorder (NNLO) to the differential cross section. The NNLO soft-gluon contributions are derived from next-to-next-to-leading-logarithm (NNLL) r...

When probed near an exclusive boundary of phase space, perturbative partonic hardscattering cross sections for electroweak-boson (γ, W, Z, H) production acquire large logarithmic corrections arising from incomplete cancellations of soft-gluon effects between virtual and real diagrams. The two prominent examples are threshold and recoil corrections. The former are of the form α s ln (1−z)/(1−z) ...
متن کاملThreshold resummation for high-transverse-momentum Higgs production at the LHC
We study the resummation of large logarithmic QCD corrections for the process pp → H + X when the Higgs boson H is produced at high transverse momentum. The corrections arise near the threshold for partonic reaction and originate from soft gluon emission. We perform the all-order resummation at next-to-leading logarithmic accuracy and match the resummed result with the next-to-leading order per...
