Gauge-Boson Pair Production at the LHC: Anomalous Couplings and Vector-Boson Scattering
نویسندگان
چکیده
We compare vector boson fusion and quark antiquark annihilation production of vector boson pairs at the LHC and include the effects of anomalous couplings. Results are given for confidence intervals for anomalous couplings at the LHC assuming that measurements will be in agreement with the standard model. We consider all couplings of the general triple vector boson vertex and their correlations. In addition we consider a gauge invariant dimension-six extension of the standard model. Analytical results for the cross sections for quark antiquark annihilation and vector boson fusion with anomalous couplings are given.

Electroweak corrections to γZ production at hadron colliders
In this paper we present the results from a calculation of the full electroweak oneloop corrections for γZ vector-boson pair production at hadron colliders. The cases of proton–antiproton as well as proton–proton collisions, at the Tevatron and the LHC, respectively, are considered. Results are presented for the distribution of the γZ invariant mass and for the transverse momentum of the final-...
متن کاملGluon induced contributions to WZ and Wγ production at NNLO
We calculate the contribution of the partonic processes gg → WZqq̄ and gg → Wγqq̄ to WZ and Wγ pair production at hadron colliders, including anomalous triple gauge-boson couplings. We use the helicity method and include the decay of the W and Z-boson into leptons in the narrow-width approximation. In order to integrate over the qq̄ final state phase space we use an extended version of the subtrac...

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 کاملHiggs Pair Production via Vector Boson Fusion at the LHC
The measurement of Higgs pair production will be one of the cornerstones of the LHC physics program in the coming years, with the upcoming high-energy and high-luminosity phase. The Vector Boson Fusion (VBF) production channel probes directly the coupling of new physics and of Higgs to gauge bosons, in addition to reducing background contribution. The production via VBF of an heavy object on-sh...
متن کاملVector boson Pair Production at Supercolliders ; useful approximate helicity amplitudes †
We study vector boson pair production at LHC and SSC, taking into account the effects generated by the anomalous vector boson and Higgs couplings induced by the operators OW and OUW , which are the only dim=6 operators preserving SU(2)c. These operators lead to enhanced production of transverse vector bosons, as opposed to the enhanced production of longitudinal gauge bosons, induced in case MH...
