  We have given a first application of the Axial gauge a` la Dams and Kleiss to
the Standard Model (SM) physics at the LHC. We have focused on the issue of
providing a well-behaved signal definition in presence of potentially strong
gauge cancellations at high energies. As a first illustration, we have analysed
the production of WZ vector-boson pairs, which gives rise to four final-state
fermions. Purely leptonic final states, pp->lvll, have been numerically
investigated in the region of high center-of-mass energies and large scattering
angles, particularly sensitive to gauge dependences. We have found that the
Axial gauge is the appropriate framework to recover a meaningful separation of
signal and irreducible background over the full energy domain.
