The Effective Vector Boson Approximation in high-energy muon collisions
/ Ruiz, Richard (Cracow, INP) ; Costantini, Antonio (Louvain U., CP3) ; Maltoni, Fabio (Louvain U., CP3 ; INFN, Bologna) ; Mattelaer, Olivier (Louvain U., CP3)
Due to the inclination for forward gauge radiation, lepton colliders beyond a few TeV are effectively electroweak (EW) boson colliders, suggesting the treatment of EW bosons as constituents of high-energy leptons. In the context of a muon collider, we revisit the validity of W and Z parton distribution functions (PDFs) at leading order in 2 → n process. [...]

Vector boson fusion at multi-TeV muon colliders

Heidelberg, ITP) ; Mattelaer, Olivier (Louvain U., CP3) ; Ruiz, Richard (Louvain U., CP3) ; Zhao, Xiaoran (Louvain U., CP3)
High-energy lepton colliders with a centre-of-mass energy in the multi-TeV range are currently considered among the most challenging and far-reaching future accelerator projects. Studies performed so far have mostly focused on the reach for new phenomena in lepton-antilepton annihilation channels. [...]

Measuring the quartic Higgs self-coupling at a multi-TeV muon collider
/ Chiesa, Mauro (Annecy, LAPTH) ; Maltoni, Fabio (Louvain U., CP3 ; U. Bologna, DIFA ; INFN, Bologna) ; Mantani, Luca (Louvain U., CP3 ; U. Heidelberg, ITP) ; Mele, Barbara (INFN, Rome) ; Piccinini, Fulvio (INFN, Pavia) ; Zhao, Xiaoran (Louvain U., CP3)
Measuring the shape of the Higgs boson potential is of paramount importance and will be a challenging task at current as well as future colliders. While the expectations for the measurement of the trilinear Higgs self-coupling are rather promising, an accurate measurement of the quartic self-coupling interaction is presently considered extremely challenging even at a future 100 TeV proton-proton collider.

In order to stimulate new engagement and trigger some concrete studies in areas where further work would be beneficial towards fully understanding the physics potential of an $e^+e^-$ Higgs / Top / Electroweak factory, we propose to define a set of focus topics. [...]

Towards a Muon Collider

A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. [...]
