“…The latter mainly originate from the production of vector bosons plus two-jets, pp → V jj and in particular W bb [406,407], vector boson pairs, pp → V V [407][408][409], top quark pairs, pp → tt [410] and single top quarks pp → t + X [388]. These processes are known at least to NLO in QCD.…”

“…The main background is due to continuum ZZ production which is known rather precisely [408,409] but which can be also directly measured from the side bands of the resonance peak and interpolated to the signal region. For M H > ∼ 600 GeV, high enough luminosities are required since BR(H → ZZ → 4ℓ) ∼ 0.1% is small and the total Higgs width becomes large.…”

“…In order to get reliable theoretical predictions for vector-boson pair production it is important to include higher-order corrections. One-loop QCD corrections, treating the vector bosons as stable particles, were computed for W ± γ production [3] and W ± Z production [4] ten years ago. Since vector bosons are identified through their decay products it is essential to include the decay of the bosons into fermions.…”

AbstractWe calculate the contribution of the partonic processes gg → W Zqq and gg → W γqq to W Z and W γ 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 qq final state phase space we use an extended version of the subtraction method to NNLO and remove collinear singularities explicitly. Due to the large gluon density at low x, the gluon induced terms of vector-boson pair production are expected to be the dominant NNLO QCD correction, relevant at LHC energies. However, we show that due to a cancellation they turn out to provide a rather small contribution, anticipating good stability for the perturbative expansion.

“…The relevance of NLO corrections was first shown for the production of real (spinsummed) W and Z bosons with Standard Model couplings and without considering lepton decays and spin correlations [7,8]. These calculations were later extended, in order to include the leptonic decays and anomalous couplings [9,10,11].…”

We present a general purpose Monte Carlo program for the calculation of any infrared safe observable in W γ and Zγ production at hadron colliders at nextto-leading order in α s . We treat the leptonic decays of the W and Z-boson in the narrow-width approximation, but retain all spin information via decay angle correlations. The effect of anomalous triple gauge boson couplings is investigated and we give the analytical expressions for the corresponding amplitudes. Furthermore, we propose a way to study the effect of anomalous couplings without introducing the ambiguity of form factors.
