AB  - Applying electroweak factorization for the quantum field theory of the Standard Model at its highest energies (when it is in its unbroken phase) speeds up calculations considerably for EW vector-boson fusion (VBF) processes which constitute the bulk of the cross section at parton collisions beyond a TeV. Furthermore, this formalism is very important for the conceptual understanding of the EW interactions at these energies and paves the way for resumming large logarithms necessary for precision predictions. We study the so-called effective vector boson approximation (EVA) for W and Z bosons inside leptons and quarks, mostly for future multi-TeV muon colliders, but also for FCC-hh at 100 TeV. Using our simulation framework inside the Whizard event generator, we study VBF processes using EW PDFs which are solution of DGLAP evolution equations containing the full chiral SM. We compare EVA with EWPDF simulations and the full partonic matrix elements, investigating where resummation effects are important.
