NLO Electroweak Corrections to Higgs Boson Production at Hadron Colliders
نویسنده
چکیده
We present the complete two-loop electroweak corrections to gg → H, the main partonic channel for the production of the Higgs boson at hadron colliders. The evaluation is based on a numerical approach and the result covers all kinematical regions, including WW and ZZ thresholds, by introducing complex masses for the W and the Z bosons. Furthermore the relation between physical observables measured at LHC and Tevatron and Higgs pseudo-observables (production cross section and partial decay widths) is revised by extensively using the notion of the Higgs complex pole. Numerical effects for the Higgs production cross section are presented.

NLO QCD Corrections to Electroweak Higgs Boson Plus Three Jet Production at the LHC
The implementation of the full next-to-leading order (NLO) QCD corrections to electroweak Higgs boson plus three jet production at hadron colliders such as the LHC within the Matchbox NLO framework of the Herwig++ event generator is discussed. We present numerical results for integrated cross sections and kinematic distributions.

Vector-boson fusion (VBF) processes have emerged as a particularly interesting class of scattering events from which one hopes to gain insight into the dynamics of electroweak symmetry breaking. The most prominent example is Higgs boson production via VBF, which is shown in Fig. 1. This process has been studied intensively as a tool for Higgs boson discovery [1–3] and the measurement of Higgs b...
متن کاملNext-to-leading order QCD corrections to Z boson pair production via vector-boson fusion
Vector-boson fusion processes are an important tool for the study of electroweak symmetry breaking at hadron colliders, since they allow to distinguish a light Higgs boson scenario from strong weak boson scattering. We here consider the channels WW →ZZ and ZZ→ZZ as part of electroweak Z boson pair production in association with two tagging jets. We present the calculation of the NLO QCD correct...
متن کاملStrong and electroweak NLO corrections to Higgs-boson production in vector-boson fusion at the LHC
We present results on the strong and electroweak NLO corrections to the production of a Higgs boson plus two hard jets via weak interactions at the LHC. The calculation includes all weak-boson fusion and quark– antiquark annihilation diagrams as well as all related interferences. We discuss corrections of different origin (QCD corrections of vector-boson-fusion type and interferences, electrowe...
متن کاملElectroweak and QCD corrections to Higgs production via vector-boson fusion at the LHC
The radiative corrections of the strong and electroweak interactions are calculated at next-to-leading order for Higgs-boson production in the weak-boson-fusion channel at hadron colliders. Specifically, the calculation includes all weak-boson fusion and quark– antiquark annihilation diagrams to Higgs-boson production in association with two hard jets, including all corresponding interferences....
