High Energy Physics Seminar

In this talk we present a picture of what life is like at a multi-TeV
muon collider. We start by showing that beyond a few TeV electroweak
(EW) boson fusion/scattering becomes the dominant roduction vehicle at
lepton colliders for both Standard Model processes and new physics
processes. Motivated by this, we revisit the treatment of weak gauge
bosons as constituents of high-energy leptons. In particular, using a
new, public implementation of (polarized) W/Z parton distribution
functions in the Monte Carlo event generator MadGraph5_aMC@NLO, we
report the size of universal, i.e., process independent, corrections
that spoil the accuracy of a (factorized) scattering formula for muon
collisions. Guided by this insight, we give an outlook for EW boson
scattering at many TeVs.

The talk is in 469 Lauritsen.
