Life at a Multi-TeV Muon Collider

In this talk we present a picture of what life is like at a multi-TeV muoncollider. We start by showing that beyond a few TeV electroweak (EW) bosonfusion/scattering becomes the dominant production vehicle at lepton collidersfor both Standard Model and new physics. Motivated by this, we revisit thetreatment of weak gauge bosons as constituents of high-energy leptons. Inparticular, using a new, public implementation of (polarized) W/Z partondistribution functions in the Monte Carlo event generator MadGraph5_aMC@NLO, wereport the size of universal, i.e., process independent, corrections that spoilthe accuracy of a factorization theorem for muon colliders. Guided by thisinsight, we give an outlook for polarized EW boson scattering at many TeVs.
