Leading-color two-loop QCD corrections for three-jet production at hadron colliders

NLO QCD corrections to ZZ+jet production at hadron colliders

A fully differential calculation of the next-to-leading order QCD corrections to the production of Z-boson pairs in association with a hard jet at the Tevatron and LHC is presented. This process is an important background for Higgs particle and new physics searches at hadron colliders. We find sizable corrections for cross sections and differential distributions, particularly at the LHC. Residu...

Next to Leading Order Three Jet Production at Hadron Colliders

I present results from a next-to-leading order event generator of purely gluonic jet production. This calculation is the first step in the construction of a full next-to-leading order calculation of three jet production at hadron colliders. Several jet algorithms commonly used in experiments are implemented and their numerical stability is investigated. A numerical instability is found in the i...

Two-Loop Corrections to Top-Antitop Production at Hadron Colliders

Two-loop electroweak corrections to Higgs production at hadron colliders

We compute the two-loop electroweak corrections due to the top quark to the gluon fusion production cross section of an intermediate-mass Higgs boson. This result, together with the previously known contribution due to the light fermions, allows a complete determination of the two-loop electroweak corrections to this production cross section. For Higgs mass values above 120 GeV the top correcti...

Threshold corrections to inclusive jet production at hadron colliders

We compute QCD threshold corrections to the inclusive jet hadro-production process in the softgluon resummation formalism. We expand the resummed results to 1-loop and 2-loop level at next-to-leading logarithmic (NLL) accuracy and compare with the results in the literature. Further, by presenting the transverse momentum distributions of the jet for Tevatron and LHC, we investigate the jet cone ...
