“…the contribution of linear terms in h V 3 and h V 4 appearing in the squared amplitudes due to the correct treatment of the i factor in the ZγV vertex [15]. For this particular configuration, the interference effects are mostly relevant at √ŝ < 1 TeV and modify the cross section by more than 10%.…”

“…For Zγ production, we consider operators up to dimension 8 (all of them C odd) resulting in ZZγ and Zγγ couplings. The non-standard Z α (q 1 )γ β (q 2 )Z µ (p) momentumspace vertex is given by [15] …”

“…[11] by an overall factor i, which ensures the hermiticity of the corresponding effective Lagrangian 3 [15]. Furthermore, the i factor modifies the interference pattern of anomalous coupling and Standard Model amplitudes: CP -violating h 1,2 contributions do not interfere with the Standard Model ones, whereas the CP -conserving h 3,4 do [15]. Therefore, with the corrected vertex, there are contributions linear in h 3,4 and the cross section is generally not invariant anymore under a change of sign of h 3,4 .…”

“…Obviously, it is possible to do such analysis for the production of Zγ when both leptons are detected. Since the center of mass partonic energy can be reconstructed from the kinematics of the final state particles 4 the cross section can be measured for different bins of fixedŝ [15]. As an example, we show in Figure 5 the cross section as a function ofŝ.…”

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.

We present the results of a complete analysis of the one loop electroweak corrections to e − e + → γγ, Zγ, ZZ in the Standard (SM) and the Minimal Supersymmetric Standard Model (MSSM). A special emphasis is put on the high energy behaviour of the various helicity amplitudes and the way the logarithmic structure is generated. The large magnitude of these effects, which induce striking differences between the SM and MSSM cases at high energies, offers the possibility of making global tests which could check the consistency of these models, and even decide whether any additional new physics is required.

The study of the scattering at high energy of the gauge bosons W and Z, in particular longitudinally polarized W and Z, can clarify the mechanism of spontaneous symmetry breaking in the Standard Model of the electroweak interactions. Different models of strong electroweak sector, based on the effective lagrangian approach are briefly reviewed. They include models with no resonance, with scalar resonance, additional vector and axial-vector resonances. The effective Lagrangians are derived from the chiral symmetry of the symmetry breaking sector. Limits on these models from existing measurements, mainly LEP and Tevatron, are considered. We study also direct and indirect effects of the new interactions at high energy future e + e − linear colliders, through W W scattering and the direct production of these new vector gauge bosons.
