abstract = {Collider processes at the highest available partonic
center-of-mass energies — 10 TeV and above — exhibit a
new regime of electroweak interactions where electroweak
gauge bosons mostly act as quasi-massless partons in vector
boson fusion processes. We scrutinize these processes using
the Equivalent Vector boson Approximation (EVA) based on its
implementation in the Monte Carlo generator framework
Whizard. Using a variety of important physics processes,
including top pairs, Higgs pairs, neutrino pairs, and vector
boson pairs, we study the behavior of processes initiated by
transverse and longitudinal vector bosons, both W and Z
induced. By considering several distributions for each
process, we conclude that: there is no universal,
process-independent prescription which minimizes the
discrepancies between EVA- and matrix-element-based
predictions; even by resorting to process-by-process
prescriptions, we typically observe significant
observable-dependent effects; the uncertainties associated
with parameter dependencies in the EVA can be as large as
$\mathcal{O}(100\\%)$, and can only possibly be reduced by
careful process-dependent kinematical selections.},
