QCD Corrections and Anomalous Couplings in Zγ Production at Hadron Colliders

The processes p p (−) → Zγ + X → llγ + X (l = e, μ) and p p (−) → Zγ + X → ν̄νγ +X are calculated to O(αs) for general ZZγ and Zγγ couplings. The impact of O(αs) QCD corrections on the observability of ZZγ and Zγγ couplings in Zγ production at the Tevatron and the Large Hadron Collider (LHC) is discussed. Typeset using REVTEX

Anomalous Couplings at Lep2

In its second phase, LEP has allowed to study four fermion processes never observed before. Results are presented on the charged triple gauge boson couplings (TGC) from the W-pair, Single W and Single γ production. The anomalous quartic gauge couplings (QGC) are constrained using production of W W γ, ν ¯ νγγ and Zγγ final states. Finally, limits on the neutral anomalous gauge couplings (NGC) us...

Four-Fermion Production with Anomalous Couplings at LEP2 and NLC1

I give a short report on the semi-analytical approach to off-shell W pair production. In particular, I show the effects of irreducible background diagrams of the CC11 class in the differential cross-section. Further, I study the influence of potential anomalous couplings at a future linear collider and investigate the sensitivity of the forward-backward asymmetry to anomalous couplings. Talk gi...

Quartic anomalous couplings at LEP

The search for quartic anomalous gauge couplings at LEP requires appropriate predictions for the radiative processes ee → νν̄γγ, ee → qq̄γγ and ee → 4 fermions+γ. Matrix elements are exactly computed at the tree level, and the effects of anomalous couplings and initial-state radiation are included. Comparisons with results and approximations existing in the literature are shown and commented. Imp...

Anomalous Higgs Couplings at Colliders

I summarize our results on the attainable limits on the coefficients of dimension–6 operators from the analysis of Higgs boson phenomenology using data taken at Tevatron RUNI and LEPII. Our results show that the coefficients of Higgs–vector boson couplings can be determined with unprecedented accuracy. Assuming that the coefficients of all “blind” operators are of the same magnitude, we are als...
