چکیده
We describe the salient features of precise predictions for the processes e + e − → WW → 4f (γ) as obtained with the Monte Carlo generator RacoonWW ‡ , including the complete O(α) electroweak radiative corrections in the double-pole approximation. Numerical results for some distributions are given at the typical linear-collider energy √ s = 500 GeV. Moreover, we study the impact of the non-universal electroweak corrections by comparing with results of an improved Born approximation. Abstract.

Higgs signals and hard photons at the Next Linear Collider: the ZZ-fusion channel in the Standard Model
In this paper, we extend the analyses carried out in a previous article for WW -fusion to the case of Higgs production via ZZ-fusion within the Standard Model at the Next Linear Collider, in presence of electromagnetic radiation due real photon emission. Calculations are carried out at tree-level and rates of the leading order (LO) processes e+e− → e+e−H → e+e−bb̄ and e+e− → e+e−H → e+e−WW → e+e...
متن کاملAnomalous Z ′ effects in the WW channel at LC 2000
We consider the virtual signals of a Z ′ of very general type in the process e + e − → W + W − at a future linear e + e − collider of 2000 GeV c.m. energy (LC2000). We show that possible deviations from the SM predictions in this channel are related to similar deviations in the purely leptonic one in a way that is only characteristic of this Z ′ model, and not in general of possible competitor ...

متن کاملAnomalous Z ′ effects in the WW channel at NLC
We consider the virtual signals of a Z ′ of very general type in the process e + e − → W + W − at a future linear collider (NLC). We show that possible deviations from the SM predictions in this channel are related to similar deviations in the purely leptonic one in a way that is only characteristic of this Z ′ model, and not in general of possible competitor models with anomalous gauge couplings.
